$400 plus when?
At the moment the Bitcoin value is around $600, the price has not been moving much the last month which is not a good thing.
People then will get bored and tired of waiting to long.
but i think still it is too good that bitoin price is so stable and not felling down any more, and now you can see that people are now showing interest in bitcoin after the bitfinex hacking and hope this time the price of bitcoin is going to create new record.
It will take some time for the people to be aware of the benefit of the bitcoin. In the long term, the value of bitcoin will increase.
