Similar thing to PALNet (I suppose you know, since you use the tag): they have their own interface (steemleo.com) and their own token, LEO. And when you make a post that touches investing in some way (not just crypto, everything investing related goes) you can just put the 'steemleo' tag and the post will be able to earn tokens (not sure if it works by adding the tag before hand, but you could try). But the difference is that it focuses on investing – in any type, not just crypto.

And Palnet and Steemleo aren't the only ones – there's a lot of tribes with similar idea popping left and right. Loads of stuff happening nowadays on the blockchain :D
