Not sure we even need 100. In the end I'd be surprised if the form of the industry wasn't three big blockchains have 90% market share
And a bunch of little niche players end up with 10% share between 40 niche players

I think steemit will be getting smart media tokens. I think those might be similar to alt coins. We'll probably have at least a dozen of those on here eventually but yeah the top 3 or 10 tokens should have a huge portion of the market share.
