-troll FUD-
The problem for the big pocketed folks is that unlike the gold futures market or the stock market you can't naked short BTC. You actually have to have some to sell or borrow.
This makes the market much harder to control hence the weekend/holiday attempts when people can't get fiat onto an exchange.
Again I agree with you. You'll notice also that these are the times when trolling and FUD reach fever intensity.
Luckily those with experience see right through it. It's the traders and noobs who get sucked in.
