Bitcoin is not as easily manipulated as other financial instruments.

Reason being, is that most traditional financial instruments are easily scaled, at a whim. Companies can issue as many shares as they want, banks can issue as much cash as they want, and a lot of it is based on nothing. People borrow lots of money and use stocks as security, and when the margins are called, the banks repossess the stocks and sell.

They can't do that with bitcoin.

If someone wants to pump and dump, they can buy enough bitcoin to push the price up, and sell enough to push the price back down to more or less where it started.

the will almost certainly be a retrace very soon. could be this weekend. But we have not reached a peak.
