I'm still learning about crypto currencies and how they work but this is somewhat concerning. I guess I've got a lot more to glean and understand, and maybe I've a fundamental misunderstanding of how the blockchain works but it seems to me that hacking should be much tougher than expected.
Still... it does present an interesting conundrum and an opportunity for learning I guess :)
One other thing struck me - how much like the existing money markets it is. With this on top of the general downward trend since December are we seeing a burst in the bitcoin bubble?
