Minds is quite a bit different from Steemit. It's possible to earn Minds Tokens, their version of Steem, but the actual monetization of that is a bit murkier. I think you can indeed exchange them for money, but the exchange rate isn't great and it's not really the typical use for a token. The main thing people use tokens for is boosting, where your post gets a guaranteed number of views on what is called the boostfeed, a feed of non-subscribed content on everyone's feeds. You can disable this on your own feed just like you can disable ads on other platforms, by signing up for Minds plus. It's worth noting you can also pay for Minds plus with tokens.

So, you basically get the option to advertise on their platform by earning and spending tokens, 1000 views for each. It's really great because it helps break out of the normal bubble one can sometimes find themselves in online, both in getting your content noticed and finding other people with interesting content.

I personally enjoy the site quite a bit, though I haven't made as much cryptocurrency there. You could always check it out, maybe read the faq for more information.
