I've been powering up Steem since I started. Granted I haven't been earning it as fast as what I could have been, but I see it as more of a retirement fund 25 years from now. I was buying in when it was USD$5 and the price drop last year scared me off buying more with my limited FIAT for the time being.
But I also see the current price as an incredible bargain and an opportunity to really invest heavily in the platform for when the price does eventually climb again. (Not financial advice, just opinion).
