Steem held in SP is protected from inflation since SP holders are compensated in other SP to offset the inflation rate.
As for the price action on the token, that goes up and down according to the market. Like all crypto, there can be wild swings. ...so HDOL (hold on for dear life) is best in my opinion. Over time, this will move up much higher...it just might go lower first.
Super thanks for the advice @taskmaster4450!
