I think a variety of altcoin will bloom, not only bitcoin, like XRP, ETH, the market capitalization has reached half of bitcoin.
Yap and i think it is the otherwise, bitcoin gave life to altcoins. It it started with only one known coin then these altcoins spawned from thin air. Maybe right know it's hard for other coins to increase via price but still. Many altcoins now have different agendas on there own. It maybe hard to control but in there own time they might actually might get high. Because technically it is still too early to decide whether coins are dying or not.
