If he is an existing person or there is a group of developer I think that is the main thing to think about. Probably he (or that group) already sold millions of their bitcoins for some hundred million. Probably I would do the same when btc price is more than 50 USD just sell all because it was already without value in the beginning.
Cok yazik olmus uzucu bir haber maalesef. Umarim yapan kisiler bulunur ve en agir sekilde cezalandirilir. Bu borsalar da kimlikleri aliyorlarsa guvenli sekilde saklasinlar bu kadar sacmalik olmaz. Kimseye guvenmeyeceksin artik hale bak..
Its not worth to mine btc anymore. I think it would almost end and will be so hard in next year. So better to leave btc mining or even cloud mining systems so far.
It doesnt mean that opportunity to buy maybe. Maybe it is going down in mid-future time who knows. Volatility is still so high and price is always unexpectible. I think in couple months it will go up again (summer season always). Hopefully noone will suffer this volatile prices.
I think he is not one real person. There must be a group of people who is coordinating this system like anonymous. But it is right that these people have lots of coins worth some billions in total.
