It's not something that I would hold as I just treat it as a vestigial currency that I'll sell right away for more Steem Power (or something else).
On a complete side note, what is the best way to turn Steem Power into USD? I'm legit confused af @kevinwong
You don't. you just keep holding SP forever. lol joking.
you'd need to power SP down, SP will turn to Steem, then trade steem for usd (likely via btc)
