FBI will sell their bitcoins one of these days.
Why will this crash the bitcoin price? Simple:
FBI got: 144,000 bitcoins.
Totale volume of ALL exchanges combined: between 70 and 80 thousand.
About HALF of what the FBI is going to DUMP.

Remember: if China sells 25,000 bitcoins, the price will drop between $200 and $250 USD.
We are talking about almost SIX TIMES (6!!) that much. It can't even drop 6 x 200 = 1,200 - that's higher than the bitcoin price!
So, realistically, the price would probably drop to around $80 because a lot of people will buy up. But not enough to make the price go back up fast enough, as 144,000 bitcoins = A LOT MORE than all people combined, on all exchanges, would be able to afford. This would lead to another drop/crash.
So sell now, it's not too late yet!
