Arbitrage to MintPal is going to be insane if that happens. Cryptsy is insanely volatile because of the types who trade there.
Mintpal is dumping to about the same level so there's not going to be much arbitrage. Also, can't do arbitrage anyways cause mintpal wallet remains closed for deposits.
you sold in the 700's and are not buying back in ? sounds like a bad decision. Let's wait and see.
