Anyone do anything with cryptocurrency

[Pat Jackson]

I hesitate to ask this, even in the "off-topic" forum for fear of ruining a reputation that I don't even have.  However here goes....is anyone trading or mining or doing anything with cryptocurrency?  Up front I acknowledge that cryptocurrency is extremely volatile.  Scary stuff really.  However many millionaires have been made in the last 5+ years, and bitcoin is getting into the news more and more.  

IOTA caught my eye....Microsoft is interested and it seems like a very interesting way to share enormous volumes of data quickly.

Anyway, just curious if anyone is in this game.
