You say that you all know about bitcoin , blockade, can you give valuable advice, correct and comment on the mistakes of others? Now we will verify this.

Now calculate the results:

29-30 points – you are either a geek who studies technology day and night or treats the pioneers of the blockbuster industry. In any case – congratulations, perfect result, not all heroes wear cloaks. Good for you of mining and excellent mood. To the moon soon!

25-28 points – if you were awarded science degrees for the crypto-currency activity in the block-industry industry, then you would become a candidate of science. You have fundamental knowledge and a vector of potential growth. The rocket has already been launched, everything will be done, but not immediately.

20-24 points is also a good result. You are obviously a regular reader of crypto-currency media, are interested in the industry, but "somewhere something was forgotten, I knew for sure, but could not remember …". We understand that the situation in the digital assets market is not the best, it makes you nervous, and annoying mistakes are made. Do not worry, the "moon" is coming soon.

14-19 points – you probably heard about blockage and bitcoin several times, discussed high cost of crypto currency with your friends, thought about investing, but something stopped you. In vain. It would be better to participate in presale campaigns, get free coins of projects, so they would be drawn into a fascinating but nervous cryptomir.

8-13 points – are you lucky and accidentally guessed the answers to the questions? Or do you have basic knowledge and want to continue studying crypto currency and blocking? Then read the materials DeCenter and DeCenter Magazine, which presents analytical articles for the newcomers of the industry as well.

0-7 points – which is "Beethoven"?
