  - I keep only a few and sell the rest for Steem
 - I prefer to keep them liquid/un-staked


I haven't sold a lot of them yet, but I think that's what I really will do. I need to keep better track of what I have (since new ones pop up all the time) and determine when it would be best to sell, since price can fluctuate quickly.

I really don't see me buying steem engine tokens, though. I don't know. If something starts to move maybe, but for the most part, it appears people are getting tokens for free and then selling them for the most part. I know some folks are actually buying, so who knows. Maybe they'll keep the market afloat until more people show up.

Not sure what SMTs are going to do to the steem engine tokens when they finally arrive, but it sounds like they're as close to becoming a reality as they've ever been.
