Why did the value of 1 BTC fall from ~1100 USD in December to ~450 now? I can understand volatility for a couple 100 dollars even, but the value has almost halved. Is this due to the Mt. Gox hacking?
Those are more speculations IMO, but I believe reasons are clear:
1. Mt.Gox
2. Other exchanges suffers attacks
3. Charlie S.
4. Then it was not bad
until5. ITS
6. China (maybe yes/maybe no)
but all of those means nothing
Bitcoin is not 1 year old project and it is very strong even with all of those issues there are plenty of good news too.
