Many projects based on Ethereum are gaining a lot of attention and have a big marketcap. Just look at augur, golem, chrono and not to forget SingularDTV!
More projects coming every week it seems, so Ethereum must go higher eventually. But over 150% more after the recent jump... doubtful.
I think it seems reasonable...Im not saying end of the month, Im saying over the next 6 months - 150% in 6 months is cake in this crypto market...we might have to re-evaluate around August or September
