Remember, holding is also using, and there are millions out there "using" BTC as a store of value. At the end of the day, the number of users don't really matter - it's all about economic activity. That's where bitcoin and ethereum are the only two chains with any significant economic activity. Hive/Steem is absolutely negligible on that scale.

Anyway, the Reddit Points will definitely be on CMC, listed on Binance etc. It's an ERC-20 token like any other, and the Reddit app clearly confirms that -

Points are a decentralized blockchain token that represents ownership in a community. They are stored outside of Reddit, they can be traded freely, and they can be used for any number of purposes within the community, without restriction or control of Reddit. If Reddit stops operating, or the community leaves Reddit, Community Points still continue to exist.

I hear you, it's possible that only the existing crypto enthusiasts actually use Points, and it goes invisible to the mainstream user. And certainly, I expect only the most savvy of Reddit users to use it. But even if 1% gets it, it's still 5 million active users! Slowly, but surely, over time, more people will start using it, and beyond a critical mass, there'll be an exponential growth. It's hard to say if that will happen, but either way, it's still a huge deal for crypto adoption.

BTT is still in its infancy with no real utility. They have some stuff planned, but I'm skeptical. I'd instead point you to BAT - it now has over half a million of content creators actively accepting BAT, some pretty big names too. The active consumers is harder to track. Note that it's still in beta and slowly rolling out. Brave is on course to hit 10 million users some time this year, and when they start actively pushing BAT, it has the potential to be another million user token.
