For what it's worth, I think the altcoin space is where the best minds and innovation are at today.
I am becoming more and more convinced that BTC will be replaced by a 2.0, or rather, probably by like 5-10 different 2.0s with different goals. Ripple, ETH, and BTS are probably among them. I do think BTC will stick around as the primary store of value coin, at least if they can get a decent resolution on block size issues.
I cant wait for BTS 2.0 to get out there and establish itself. We need to be generating the level of interest that ETH is currently!
