After writing this, I remembered that I own some CANNA tokens (on the steem-engine site). I've been earning various tokens for my posts (like WEED, LEO, BEER, etc), something we're all doing even if we don't realize it. I've been converting mine (at current market rates) into CANNA tokens, something I see as stable because the price doesn't usually fluctuate much. The way the token is set up, growth is fairly slow, but steady. So I don't really consider that investing, more like earning, and then saving. At some point I'll cash out for something else, of course. I have about $20 worth at the moment, going up by about a dollar per week. Figured I'd mention it!
