You make a pretty good argument. I think it will take some time until steemit can transform more towards other topics besides crypto. Note though this is already happening. When we search through "explore" on steemit one can see most payouts are in topics besides cryptos. Although bitcoin and cryptocurrency still remains pretty high.
I think steemit can work both ways. Be a gateway for crypto news and non-crypto topics. I hope in time people realize that steemit is more than crypto and more users will flock in and participate.
Thanks.
