I was never really into crypto before I got started on Steemit, so I had not really been aware of how good this blockchain technology was until very recently. A few days ago I bought my first ETH to get some cryotpkitties, and man, my first time using the Ethereum blockchain was not good. It was extremely expensive to get transactions done, and I even had to try a few times to get it done (while having to pay a transaction fee even if it failed). I missed the Steem blockchain after using it for only a few minutes!
The story above is the reason why I think it will succeed. Once people just start using it and we get the ball rolling, then there's no going back to the "worse" blockchains!
