Bitcoin is dead according to Mike Hearns, could this be the turning point in which bitcoin becomes just another altcoin and the altcoins will rise up and take away the market cap that belonged to bitcoin?

Totally agree. Question for OP, what alt do you bet will win? I'm all in Ethereum, it's the most advanced coin out at the moment, highly recommend. I invested 30,000$ back a few months ago after
minergate support mentioned they were going to add it, so glad, that investements now worth over 100,000$, and no plans of selling!
