the increase is happening right now is the impact of increasingly widespread use of bitcoin. bitcoin user now has become so much more. demand will increase so raise the price of bitcoin bitcoin few days.
I think if bitcoin price continue to increase even at a single dollar per day, people will take notice and will start jumping to the new bubble train again. It has been sometime since the bad press so we can think that bitcoin price will be in an uptrend in the following weeks until badpress happen again. Bitcoin price will hit 700 USD soon.
