Why would these blockchains need to compete? Is there not enough people in this world that diversify in different manners! Maybe some people won't want to create quality content and will just spend their hard earned money to buy shares in a blockchain. I think there's plenty of room out there, for competition. But right now, and in the future, my time and my passion is in Steem. The friendships built here are more important than power. Preach it Task. 😎
