CEX.IO Bitcoin Mining Return on Investment Calculation

January 20, 2014

Latest Update: March, 17, 2014
An Interview by the CIO Jeffrey Smith. Now CEX.IO offers futures on GHS Mining.
For next month April 26th 1 GHS is now at 0.008 BTC and for 26th of May, 1 GHS trades at 0.004 BTC. Today the price for 1 GHS is at 0.0129 BTC.

Currently the price for 1 GHS today on CEX.IO  is 10.76 USD (0.017193 BTC / Bitstamp: 626USD / BTC). If you buy a KNC Miner with 3 THZ for 13 000 USD you will pay 7 USD/GHS which is just lower than 3.76 USD/GHS on CEX.IO . However on CEX.IO you do not have to look after the equipement and you can sell your GHS at any time. The price for 1 GHS used to be 4 times higher on CEX.IO versus bying your own equipement now it is down to 1.537:1. At this ratio you are better of trading GHS on CEX.IO .  It looks like we are hitting a bottom in price on CEX.IO as miners will very likely not sell their GHS on CEX.IO below or at the same level as their equipement costs .

Status of my investment in January: I am below my investment due to the drop in prices per GHS on CEX.IO. Please see the list of cautions at the end of this post.

Status 20. January 2014: As it stands of today I am about to make around 199% on my investment in Bitcoin Mining at CEX.IO .
On the platform CEX.IO you can instantly buy so called hashrates (GHS) of computer mining power or if you do not need those sell them again.

I bought 1 GHS on January 17th and after 3 days mining I am currently at a 199% return of my investment. I paid 0.0455  BTC for 1 GHS. And I will continuously update the calculation.

At CEX.IO you are not only mining Bitcoin BTC but at the same time 3 other cryptocurrencies are mined. These cryptocurrencies are Namecoin NMC, IXCoin IXC and Devcoin DVC.

After 72 hours of mining I have:
0.00073126 BTC
0.001148024 NMC (Namecoin)
0.00578684 IXC (IXCoin)
0.21625056 DVC (Devcoin)

After converting the NMC (exchange rate on CEX.IO) and the other cryptocurrencies IXC and DVC (exchange rate on into BTC I mined so far 0.00074321.
Based on the current amount of BTC mined I would make a 199% return of my investment in 1 year. What I have not calculated is the effective interest rate. The payouts of the mining is immediately, therefore the effective interest rate should be above 199%. As you have a constant payout of the BTCs mined – a fraction at least once per hour, the payout now has always more value than if you get paid in the future. As an example if you invest in shares and hold them for a year you will only get paid once per year the divident of the share and only realize any gains of the share price after you have sold you shares.

Also if I would sell my 1 GHS now I would also make a small return as the current price for 1 GHS is now at 0.04367. Plus if I would change the BTC back into USD I would make an additional return as the rate for BTC against the USD recently went up.

Before you get too excited there are some words of caution.
Please consider these risk factors:
With the increase of mining power added continuously the return from mining Bitcoins BTC with 1GHS could decrease over time. This might be the case also for the other cryptocurrencies.
The value of 1GHS can decrease.
The value of 1 BTC can decrease against the FIAT currencies.
Theft. Your account could get hacked.
The provider needs to stop services due to legal constraints or goes out of business.
Your assets are not secured nor is the legal framework fully cleared.

Also consider there is 0.0001 BTC fee for withdrawal of BTC from your account at CEX.IO.

When I worked with just a few of these tools with one person the results were more than astonishing. In one year this person reached three of his major life goals while we had together estimated five. Why shouldn’t you achieve the same ?

After you have read through this article you will be twice as likely to reach your dreams, visons or goals. Given what we know today once you apply these tools I believe you will have a 95% chance to achieve your major goals in life.

It was a few years ago when the person came into my office. He was almost certain that he would quit his job because he had enough of sales. It was not his dream job. He felt tired and he had lost his passion. His intention was to join a business school fulltime, spend all his savings to major in marketing so that he could start a career in the marketing function. I listened intensively without judgement and asked questions when I needed to better understand the points he made. We sat together for 50 minutes and almost at the end of the meeting I said,” well, it seems that you have made up your mind, but is this the only option you have ? Is this the only way and what is the likelyhood of success ? Would you like to take the time to explore more options that will give you a much higher chance of success ?”. This was the moment he realized he came to have the meeting with me to just seek confirmation of his decision and not help. This was the moment when he suddenly started to listen. First I explained him the risk of his only option and then I asked him if working in marketing is his final dream in life or if it was an enabler for something bigger ?
I proposed him to find a better way to get him to the place where he really wanted to be in life if he would spend just a few hours over the next months together with me. We applied a few of the tools which helped him to become very clear what he wanted from life. It was not only a career in marketing, he also had the wish to work abroad, stay with the current employer and get married.
We met three times over the next month for only 60 minutes each.
One year later he got married, the current employer send him to Asia to work in marketing and paid for the tuition at a well known business school for his degree in marketing.
In essence good reflection takes only little time but gets you much further than we tend to believe.

I have seen these successes over and over again in my many years long career in talent management & people development and as a coach ( . Each time I am still astonished. It is magic. The method and tools are amazing. I let the person decide on the timing when to meet again and never will I judge or take the lead in the journey. It only works if the true person comes out and the true person goes through his own reflection. In my many years of experience I learned to become the sparring partner on the right level, that keeps the ball in the game. Seeing someone win, seeing someone reach his vision and goals is personally my biggest joy and fulfillment.

I didn’t have the book “Finding Your Element” by Sir Ken Robinson then. It is a great source and therefore I listed some of the resources below. I have also used additonal tools which I will go to introduce over the next couple of weeks in this blog post. My starting point is always the situation, the context the person is in and get a full understanding of it. Often this is the first time people talk to someone who is non-judgemental about it. Only then when everything is understood will I ask the person to take a helicopter view of his life. Afterwards there are a number of tools to become more specific who the person is and how he wants to go about the journey.

As we haven’t met personally I have made the following assumption about you as the reader:
- you feel like you are underutilizing your capacity and have not turned it fully to your advantage
- you are critical of yourself and you deserve to be admired more
- at certain times you have serious doubts if you have taken the right direction in life
- you feel insecure and you see your personal weaknessess which you like to hide
- you can become dissastified by restrictions and limitations
- you would like to change and add more variety to your life
- you are an independent thinker and you only accept statements with satisfactory proof
- you have great aspirations which you find pretty unrealistic and you need to provide security to yourself and others

If you agree or disagree with my assumptions you can reach out me at or leave a comment below.










Would you like to invest a few minutes of your precious life and turn it into something that you value much more ?

Being in your element, feeling engaged, having a purpose, …
In the following you find a number of tools:
You can use them on your own or with somebody you trust.
How many books have you read with exercises, but honestly how many of these exercises did you do on your own?
It seems most people like to do  exercises with someone else because they are more engaged, get more inspired and creative.

This is still my scrabble blog post, it will envolve over time:

Accept the situation you are in. Become mindful and understand your judgement.

Start with the end in mind

Aspergers Education Strategies

January 1, 2014

Tips by Dave Angel
Children with Aspergers need certain things in order to receive a proper Aspergers education. Their behavior is hard to understand for some parents, but once they gain a better understanding of children with Aspergers, they can begin to help their children the way that they need help. Here are a few suggestions that can help parents help their students with Aspergers.

� Don’t expect eye contact. Their lack of eye contact has nothing to do with disrespect, but it has everything to do with their Aspergers. Use probing questions to make sure they understand what is expected of them instead of using eye contact as an indicator in their Aspergers education.

� Every child is different from others. Parents should take the time to get to know their children with Aspergers so they understand how they think and operate. Do not put them in a category with your other children or educational failures will occur.

� Use visual cues when at all possible. Children with Aspergers are usually visual learners and they depend on these cues in their Aspergers education. They have difficulty processing oral language so hands-on, visual cues are a tremendous help.

� Do not ask them to show their work on math problems. Children with Aspergers have the ability to come up with answers by processing the information in their heads. They may not even understand why you want them to show their work. A better solution is to ask them to explain the process to you. Do not waste time trying to get them to do something that will result in an unnecessary argument and nothing more.

� Parents should allow frequent breaks. Children with Aspergers may need to take breaks as a part of their Aspergers education. Sometimes they have problems with focusing on tasks so allowing a break when they need it is a tremendous help.

� Always try to minimize sensory distractions as much as possible. Ticking clocks, tapping pens, crumbling paper, and other things can be a huge distraction for children with Aspergers. It is impossible to control all sensory distractions, but when at all possible, minimize these distractions.

� Use the IEP as the model for their Aspergers Education. This is their individualized plan for educational success so parents should take advantage of using the IEP.

� Minimize change as much as possible. Allow some transition time before asking a child to do something that is out of their normal routine. Parents should always plan for change as far in advance as possible.

Parents can help their children receive a proper Aspergers education by using a few simple strategies to ensure the success of their children. When in doubt, refer to the IEP or speak to a special education staff member for guidance.

Work Smarter, Get More Things Done through Less Than 10 Minutes Cardio High Intensity Interval Training HIIT Workout Routines in the Home Office – Latest Research

November 2, 2013
Exercise in Home Office

Creative Commons: 2010 Picture by lindsay.dee.bunny

You have looked forward to your next home office day. This is the day where you want to get all these things done that are usually difficult to achieve at work. You have planned to read a key report, fill out budget plans, answer important emails, do some key research or prepare your next presentation.

All in all you have this long list of important things you really want to get done with but as soon as you sit at your home office desk you realize that you are lacking the energy and concentration to fully focus on your work ahead. You read and read but you seem to never caputre anything as your mind is wondering off again and again. You start writing an email, but suddenly you find yourself staring on your blank page because you are struggling to form any sentences.

This is the moment you know you should have either stayed in bed or you would have been better off taking a break, go out and run or drive to the gym and exercise.  While you debate this thought you notice that the weather is not in your favour nor do you feel like packing your bag, drive to the gym, do your workout, take a shower, come back afterwards. On top of it you start to feel guilty as work is not going as planned and it seems illogical and prohibitive to you to spent the time required to go out and exercise as every minutes count. Your emails mount, calls are unanswered and you know that you have a deadline just ahead of you. This is a dilemma, neither can you get your work done because your mind is empty and tired nor can you invest the time for exercising in the gym.

What do you do ?
The good news is, there is new research on exercise. The Massachusetts General Hospital examined the metabolic response of 70 participants. Just 10 Minutes of high intensity training changed the positive metabolite signatures in the blood significantly.  This metabolic change leads to an improvement of insulin sensitivity (niacinamide) and fatty acid oxidation (loose calories faster) and a number of other healthy metabolites. And most importantly the positive effect will continue to last for 1 hour after the exercise while at the same time people feel better and more energized during this period.

Don’t you want to feel better for one hour and overcome procrestination?
Instead of going to the gym whicht takes a lot of time or run in the rain or snow you can just do a short cardio high intensity workout in your home office for less than 10 minutes.

I have tried it myself and was surprised how much more I got done in the one hour after the excercise.

With this new surprising insight I asked myself what would happen if I repeat the workout after every hour of work. Will I still experience the positive effect for the next hour after my excercise ?

To make a long answer short, yes I did. At the end of the day I got lots more things done than planned while at the same time my fitness increased. And on top of it I did not feel tired but joyful in the evening.
And also the next day I could repeat the same sequence again even with more sets than the previous day. I was quite surprised. It seems the 1 hour recovery time between each of the sequence will allow to continously increase the workout eventually over time.
If you have the opportunity to work out over several days in your home office you will also have the positive side effect of loosing weight.

But before you jump into exercising and this is my long answer there are a few things to consider.

First of all consult with your doctor if you have constraints in your flexibility or any other chronic diseases etc. and second it is good to know some of the key principles for cardiovascular training and high intensity interval training (HIIT).

Key principles for cardiovascular training

Muscules involved

The amount of muscles involved should be 1/6 of all your muscules. If you train your two arms this would account for 1/6 of your muscules or you two legs.

Threshold Heart Rate

The heart rate during the exercise should be based on your biological age which can differ from your true age. Here it is probably best to consult with your doctor or if you want to start right now just take your current age and substract it from 170 for a very rough estimation.
In the exercise you should reach at least this calculated heart rate.

Key principles of high intensity interval training

“HIIT is a form of cardiovascular exercise alternating periods of short intense anaerobic exercise with less-intense recovery periods. Usual HIIT sessions may vary from 4–30 minutes. These short, intense workouts provide improved athletic capacity and condition, improved glucose metabolism, and improved fat burning. (Reference: Wikipedia).

The HIIT workout routines at home listed below will last between 4 to 8 minutes and not more. 10 minutes is not a dogma when you can get the same results in 4 minutes. There are exercises that will include 1/6 of your muscules and will get you over the threshold heart rate.

It is up to you choose if you just do one or several workouts during the day and it is up to you decide what type of exercises you select. I have collected my exercises from several sources. It does not matter if it is from pilates, yoga, qigong or any other type of workout regime as long at it follows the key principles of cardio vascular high intensity interval training. The key is to have a warming up phase before you go into any intensive workout. If you have any other suggestions please share.

Workout Routines My Plan (for my resources see below) -
Between each sequence I wait at least for 1 hour

1. Sequence: Warm up 3-10 minutes
Warum up with Yoga
Salutation to the Sun – Surya Namaskar (Step by Step Guide with Pictures)  (Video)
Cardiovascular training and warm up (recommended by Aladar Kogler, Ph. D. – U.S. Olympic Coach)

2. Sequence: Legs 3-6 minutes
Burpees by Mark Lauren (Video)

3. Sequence: Stomach (Core) 3-8 minutes
Warm up with Yoga
Yoga Breathing Agni Sara (Video)
Workout Example (Video)
I do the first 4 exercises in the video.

4. Sequence: Shoulder 4-10 minutes
Warm up
Yoga Shoulder Stand Sarvangasana (Video)
Lift arms sidewards and circle in one direction and then the other
Circle shoulders with hanging arms
Take two books or bottle of water one on each side and lift arms sidewards
upwards as many times as you can
Take two books or bottle of water and push arms upwards as many times as you can

5. Sequence: Chest
Warm up
Yoga Chest Expander Parsvottanasana (Video)
Leg-Kick Pushup (Video)

6. Sequence: Buttock / Butt
Butt Workout (Video)

7. Sequence: Back
Warm up
Yoga The Cat Cow Pose (Video)
Lie on your stomach face down and lift both legs upwards as many times as you can.
Lie on your stomach face down and lift your upper body and head upwards as many times as you can.
Lie on your stomach face down and lift your right leg and left arm and then your left leg and right arm

8. Sequence: Arms
Seated Triceps Dips Workout (Video)

9. Sequence: Calm Down
Yoga Salutation to the moon (Step by Step in Pictures)
Meditation 3-5 minutes

This is an ideal number of sequences. Not every day often will permit to go through all the 9 sequences due to meetings and other committments.  Just select a few and do the other exercises on another day.

The focus is clearly on getting energized for the next hour and to be more productive at work. If you would combine all nine sequences and complete those in hour the effect will not be same. Usually after such a longer workout the energy will first go down before it will go up again. So instead of cramping all the exercises into the evening by spreading those across the day the impact is much higher and you reach much higher energy levels immediately after the routines.

I have done competitive sports when I was young and I was in the national team for a period of time. I also had the opportunity to watch closely the workout routines and practice from World Class sportsmen in the training camps I went to.
One thing I observed is the same that Aladar Kogler wrote in one of his books: “Those athlets who place an undue amount of importance on their results suffer and those who achieve stable, constant performance look at their sport as an important, but not the only, part of their life”. Treat your workout as a journey, a journey from hour to hour and just observe what is happening. Treasure the experience and keep a diary about the feelings and the energy after every workout. With the time you will find your best workout routines and probably after the first day you will already feel the energy coming back.

How to join with Skype in a Google Hangout Gtalk Video Chat ? How to invite people in a Google Hangout without a Google account ?

October 13, 2013

Not everyone is on Google and many use Skype. There is a way to combine Skype and Google hangout and even use other gtalk video chat tools to include people in a google hangout meeting. On top of it I am looking for ways to go beyond just the 10 maximum participant who can join a Google Hangout gtalk video meeting at the same time. I want to find ways for a DIY MOOC (Massive Open Online Course) or DIY Massive Open Online Meetings and Workshops with the lowest costs possible.

If you are a skype user without a google account you will need someone to setup a PC as below in order to dial in.

1. Download and Install Virtual Audio Cable Trial Version:

2. Download and Install manycam:

3. Download and Install Webcammax :

5. Open the Virtual Audio Cable Control Panel and create two cables in Driver Parameters upper left corner of the Panel. Then select Set. As this is the trial version and you do not have administrator rights you need to restart your computer. After the restart open Virtual Audio Cable Control Panel and it will show two lines.

6. Start Google Hangout:

7. Open Skype

8. Start Audio Repeater from Virtual Audio Cable Program Menu. Select vor Wave In your Microphone  and for Wave Out Line 1 in the drop down menu.

9. Click start in the Audio Repeater program.

10. Go to Skype, open Options under Task menu. Select Audio options and select Line 2 in the drop down menu for your speaker. Save.

11. Now Select Calls in Skype Options and select automatically accept incoming calls and also accept and save.

12. Go to Google Handout. Open Settings. Select LIne 2 for your Microphone and Select Webcammax for your webcam.

13. Open Manycam. Select in Sources Tab the item Desktop. Select on the right the icon for customize selected area. Then put this customize capture area over the location of google hangout, where the hangout video will be displayed.

14. Go to Skype and again go to Task and Options. Select Video options and enter as your video source Manycam.

15. Open Webcammax and select there the capture icon on right pane third icon from the top. Select there in the drop down menu selected area and put this area over your skype window where the video will appear.

The main principle is: Webcammax will show your Skype Video Area in the Google Hangout and Manycam will show your Google Hangout Video Area on Skype.
The consequence of this is that you as the host of the Google hangout finally will not be seen in the hangout via your webcam. You need to connect via another computer and webcam to your Google hangout or use Skype via another device such as an iPhone to call the Skype account on your PC in order to be visible in the Google Hangout.

Please note the link to which is mentioned in the youtube video remarks below is not working or will direct you to some strange Advertisements. Better don’t use it.

This is the best source – will explain in detail how to setup a Google Hangout with Skype: Combine Skype and Google Hangout

How to use manycam:

In order to include and connect several Google Hangouts you would need to setup several PCs the same way. Via Skype you would call the next Computer, etc. In this setup Skype will be the bridge between several hangouts. The intriguing part is that you could have a large group of people which receive all at the same time an opening message via Video in the different hangouts. Later they could use these different hangouts as Break-out Session by shutting down the Skype connection….

The Raspberry Pi as W-Lan AirPrint Print Server – Project

October 9, 2013

I have now a W-Lan Print Server for my home office and can print from different devices such as laptops and iphones and iPads on the only printer available.

I found this the most useful link:

SD Card 4 MB for Raspberry Pi

Debian/Raspbian Version 7 – Wheezy

Linux Print System CUPS (Common Unix Printing System)

Driver for Printer HP Color Laser Jet CM1312 MFP
Printer needs to have an USB interface

Thes steps below have worked well for me to setup up the Raspberry Pi as W-Lan Print server.

First of all once the Raspberry has booted up, you need to click on the Terminal icon. Once the terminal window is open I entered the below commands:

1. Update Raspberry PI Linux Version:
sudo apt-get update

2. sudo apt-get upgrade

3.sudo apt-get install foomatic-db

4. sudo apt-get install foomatic-db-engine

5. sudo apt-get install foomatic-filters

6. sudo apt-get install cups

7. sudo apt-get install cups-pdf

8. sudo apt-get install cupas-driver-gutenprint

9. sudo apt-get install hplip

10. sudo apt-get install pycups

11. sudo apt-get install python2

12. sudo apt-get install python-cups

14. sudo apt-get install avahi

15. sudo apt-get install avahi-daemon

16. sudo apt-get install avahi-discover

17. sudo apt-get install libnss-mdns

18. sudo usermod -a -G lpadmin pi

19. sudo /etc/init.d/cups start

20. sudo /etc/init.d/avahi-daemon start

21. sudo nano etc/cups/cupsd.conf

22. Make changes to the conf file according

23. Press CTRL+SHIFT+X

24. Press SHIFT+Y

25. Press Enter

26. sudo /etc/init.d/cups restart

27.Get IP Adress of Raspberry Pi: type ifconfig

Connect Printer via USB to Raspberry Pi USB Port

28. Go to another Computer and type in the browser: IP Adress of Raspberry

29. Select Adminstration Tab

30. Add Printer

31. username: pi  password: raspberry

32. Select Printer, etc.

33. Windows Add Printer:

34. iphone: Open an email and select the reply arrow and then print. I needed to select once my Printer HP_Color_Laserjet_CM1312_MFP and then press print button. It was dead easy for me compared to step 33 for setup of printer in Windows.

I am still researching on AirPrinter….

Is Overcoming Change Resistance Really the Key in Change Management?

August 22, 2013

Lately I was even more involved in Change Management than usual. But the more I am involved in it the more I doubt the current focus.

Over the last 20 years the main item “we” talked about was how to overcome the change inertia, the resistance, how to create a burning platform, how to communicate to resistant people in the organization and how to get them to embrace the change ?

But just take an example from private life.
How many people with a burning platform about their current weight fail in dieting ?
According to statistics up to 90% of the personal weight change management initiatives eventually fail.

 Recently I came about a 3 years study on Change which sheds a new light on change management:

The Research Study
On the Outs: Learning Styles, Resistance to Change, and Teacher Retention (2009)

This study included 237 elementary and middle school teachers and the change was about implementing an intensive school wide technology and media integration model in schools  .

MBTI (Myers Brigg Type Indicator) was used to identify the Learning Style of the teacher and Oreg’s RTC (Resistance to Change) Scale was used to measure the Change Resistance of the individual before the start of the change initiative.

Impact on Retention: It was not the resistance to change that was key in teachers attrition but instead their Learning Style was the key indicator. Teachers with the ST (Sensing-Thinking) learning style were three times more likely to leave their schools compared to teacher with other learning styles.

How to address the challenge of Sensing Thinking (ST) Individuals in Change see the full research paper (second link below).

Please find more detail on the research here:

The full research paper is here:

Would love to hear your thoughts.
