$350 is likely for ethereum. The price recovery has been so easy for bitcoin and other altcoins are also being influenced by that recovery of the king. And if the dominance of bitcoin decrease all over the market, expect that money will come in to altcoins.
I think we al are waiting for this (atlcoins grow) as Bitcoin only for big whales nowdays. And when are you expecting Bitcoin dominance decrease? In last bullrun altcoins were growing like crazy together with BTC....
