How would we know? How certain are they? We can't tell because nobody/no one would say how many bitcoins he/she has on his/her hands
Thatbis a very interesting topic that you have there. I cannot say anything in this topic but to ask too if this is a truth and on how do they acquired that huge amount of bitcoins. As far as i know bitcoins are untraceable in soem illegal transactions or maybe they have an inside man so everytime that bad guys transact in bitcoins in illegal activities the fbi interrupt and collect all their bitcoins. If they are doing that for a good cause i am going to be gppd at it because it is for the sake of may but if just for themselves i dont think so.
