I know I am being a bit dramatic. I see each blockchain as potential alternative economy to the mainstream and right now Bitcoin is the gateway, the one that bridges the fiat world to the other blockchains. Just like the dollar is the bridge for international commerce.
The moment when we start building those bridges and start focusing more on Steem and SBD as currencies and less on it's social media use case the Steem blockchain will grow and start to reach it's full potential.
