OP is saying the recent rise in prices has to be a bubble. I disagree. There may be one coming up in May/June, which can be named "Halving Bubble 2016". But at this point, we are still in a recovery phase from the bottom, there is no bubble yet.
I agree, there is indeed a rising to an upcoming bubble but I don't think this will happen this year anymore. I'm going for the mid of 2016 as well.
I'm glad to see the progress bitcoin has made so far though, this just proves that bitcoin can take a hit and can bounce back up.
