After Mike Hearn's bitcoin exit, several altcoins have performed pretty good (eth, xem , dash, xmr, even doge f.e.), Either its just pump and dump or people are going to diversify cryptos in higher amounts as before.
There are more bubble canditates showing similar chart patterns, f.e. also see XMR
Also watching NXT which shows similar signals.
Be aware that btc could go down meanwhile reducing profits.
staying long here but expect resistance at ma200
