Wow this is guy is rich yes this will have an effect to the value of bitcoin if this guy sell it, it will add to the total circulating supply, how did you get the .57$ drop? the .57% of the current bitcoin circulation is 296041 btc? i want to know what is the computation of this thank you.
Yes there is a very significant risk if some of these whales began selling. I believe however that these guys are not stupid, they have been in and watched this market for a long time. If they want to or need to sell they will do it slowly over time.
