Dan, I want you to read my post about PoW vs PoS and see if you agree with my statement that bitcoin has likely already died and people just don't know it yet:

My position is also that proof of stake has no inherent value at all, but I don't consider Steem itself a pure proof of stake system, but Bitshares would be. So in summary, whether Steem has a good or bad economic system and lives or dies, I believe Steem was a much more relevant invention of yours than Bitshares in the grand scheme of things.
