I remember when Silk Road was closed BTC price plummeted sharply but then restored quickly and started new growth cycle. This time might be the same.
MtGox generated mostly negative news background so damaged Bitcoin reputation, therefore I think now BTC price will be freed from this deterrent factor and can reach new all-time high soon!
The question is whether MTGox is going to close or not. It has more life's than a damn cat
(Of course, if it finally closes as it seems, it will be good for long term!)
