And as for manipulation, I think this recent drop is more like a return to reality. BTC needs to be converted by miners more and more to cover investments, and there are more security concerns every day. Even a fairly well known crypto site (cryptothrift) just had a security breach resulting in the loss of 15BTC. Minor, yes, but these are happening daily.
Ugh hello it's 2014 already, a year when nobody loses bitcoin to hackers any longer. Multisig, it's like a 2FA that everybody uses for online services, only for accessing coins. 2 keys, zero hacker problems.
