It is obvious that he is trying to maintain the price at below 6 so he can buy it all slowly...
Possibly.
We just screw that guy, and buy everything, including his 16k BTC wall.
I'm all for people throwing money at bitcoins. Just make sure it's money you can afford to lose.
I am sure that this will trigger another exponential rally, and then we will have sufficient profits to repay whatever we got of loan to do that feat (yes, I got loaned money to buy 600 BTC... I cannot get more loan... so now I am counting on you people doing the same).
Bitcoin is a high risk and highly speculative investment. There are no guarantees. Where people previously saw guaranteed price rises and returns (based on difficulty increases) some got burned quite badly.
