Hey Peter, yeah, predicting anything has a good chance of failure. However, I do expect Steem to do about as well as Wordpress. I think wordpress is a great example to pay attention to with regard to Steem's potential, and the Steem plugin for wordpress was one of the wisest things that could have ever been developed, but whhile that is happening @ned is going for a widget that would easily exist for any site and give Steem functionality. That's very promising.
Honestly, I see Steem as more capable of spreading throughout the internet than any other crypto, where I think Steem is doomed is the outside world. I see BCH and ETH expanding into the real world in a lot of ways, but I think Steem will experience a ceiling on that market.
