Yhea....no. Because they are in YC doesn't mean nothing. Really it could be the NASA or the FBI or whatever. If there is money in it (specially untraceable money like bitcoin) someone will hack it.
I'm not sure I like this handwavey security argument. There are lots of services handling money that don't get hacked, at least not in ways that cause a loss of said money. Treating being hacked as a foregone conclusion is rather bad practice.
Its a poor argument to try to excuse the Bitcoin community's abhorrent record with security (sans the actual Bitcoin protocol, which is quite secure).
