1  Bitcoin / Bitcoin Discussion / ⚡Cambridge Bitcoin Electricity Consumption Index - does Bitcoin boil the oceans? on: July 05, 2019, 07:41:22 PM
I'm happy to announce the release of the
Cambridge Bitcoin Electricity Consumption Index (CBECI)

by the Centre for Alternative Finance, Cambridge Judge Business School.

The index provides a real-time estimate of the total annual electricity usage of the Bitcoin network. The index has been developed in response to growing concerns over the sustainability and environmental impact of Bitcoin mining:

The website features a Comparisons section to help visitors independently assess the relative magnitude of Bitcoin’s electricity usage. The Model is reviewed and transparently updated on an ongoing basis. The CBECI is a collaborative project that is open to feedback, suggestions, and constructive criticism. To help refine the analysis, we would be interested in getting your insights on the followings:

1) How much do you pay for electricity (USD / kWh)? From your experience within the industry, what do you think is the average price paid by miners?
2) Beyond marketing figures, what is the true efficiency of mining equipment (please see and leave comments on this spreadsheet)
3) How do you estimate the Power Usage Effectiveness of your data centre?
4) For data centres in your region, what electricity sources are being used and in what proportion?

Looking forward to your feedback!
2  Economy / Trading Discussion / What kind of stop-losses do you use? What kind of software? on: March 06, 2018, 04:46:55 PM

As I'm digging deeper to trading, I understand the importance of stop-losses. I also calculated, that your strategy can benefit from moving stop losses higher while the goals are reached. But how can I do it without rush and automatically?

What is your experience with stop-losses? What kind of software do you use to do it, because Bittrex by default doesn't have such a functionality?

Will appreciate your suggestions

Hi guys,

Could you please share your findings as for the TA tools: do you have any decent strategy to follow.
Honestly, I'm not much found of TA, the more I read, the more I think that it is random.

Will appreciate your help,

6  Economy / Economics / "Guess 2/3 of the average" game results [conducted among CC-related people] on: January 25, 2018, 11:12:21 PM
The experiment we conducted is related to the Keynesian beauty contest which was devoted to explain the price fluctuations in equity markets. Keynes described the action of rational agents in a market using an analogy based on a fictional newspaper contest, in which entrants are asked to choose the six most attractive faces from a hundred photographs. Those who picked the most popular faces are then eligible for a prize.

A naive strategy would be to choose the face that, in the opinion of the entrant, is the most handsome. A more sophisticated contest entrant, wishing to maximize the chances of winning a prize, would think about what the majority perception of attractive is, and then make a selection based on some inference from his knowledge of public perceptions.

Keynes believed that similar behavior was at work within the stock market. This would have people pricing shares not based on what they think their fundamental value is, but rather on what they think everyone else thinks their value is, or what everybody else would predict the average assessment of value to be.

Later on, the experiment was upgraded to so-called “guess the average game” that has been conducted several times on different audiences including the audience of Financial Times readers [Richard H Thaler, 1997. The average guess was 18.91].

We decided to check if the answers of those who are interested in cryptocurrency issues differ from the known audiences’ answers. We’ve conducted the experiment with 2 audiences: “LinkedIn cryptocurrency-related people” and “traders of one of the Ukrainian exchanges”.

We’ve asked following question:
“Guess a number from 0 to 100, with the goal of making your guess as close as possible to 2/3 of the average guess of all those participating in the contest. (To help you think about this puzzle, suppose there are three players who guessed 20, 30 and 40 respectively. The average guess would be 30, two-thirds of which is 20, so the person who guessed 20 would win)”

The prize for the closest guess for the 1st audience was 0.1 ETH and 10 KRB for the 2nd audience.

From the 1st audience, we’ve received 643 answers. The average guess is 30.19 and the winning number is 20.13. The winner answered “20.1”, which differentiate him from 29 people who answered “20”. The answers distribution is given below:

From the 2nd audience, we’ve received 310 answers. The average here is 39.74 and the winning number is 26.49 (which is more than 6 points above the winning number for the 1st audience and almost 14 points above the Financial Times readers winning number—12.6).

There are 6 winners who tie with the answer “27”. We’ve contacted them in order to proceed with the payment. The distribution of answers is given below:

Most of the participants are the 1st level depth of reasoning and the winners are the 2nd level depth of reasoning, unlike the audience of Financial Times readers from Thaler’s experiment (they are 2nd and 3rd levels correspondingly).
We would appreciate your comments:
Why have you chosen this specific number?
What do you think justifies such a big difference?

You can also participate in the so-called second round among those, who are acknowledged with the results here:

As a lot of trading newcomers last days joining this community, I'd like to speak to you in a SEC manner: be careful, it still high risk investment. My question is: are you ready to global exchanges switch-off during the massive, universe dump?
