And also don't forget that it does not take 50 actual billions to move the price to 10k, it just takes as much as orderbook depth on all exchanges, and that is usually a tiny bit of the total amount of coins (right now, about 1% of coins are in asks). So the approximate amount of money needed to take us to 10k today is about 500million only. Of course, there will be crashes and new coins would be coming to exchanges once the price grows, as happens now at 1k, etc etc, so to get the actual sustained value of 10k per coin there has to be several billion incoming, not 100 though. Still pretty realistic.
