Yup :-) I quadrupled my initial STEEMPOWER in 300 Days. In the same time the price of STEEM tripled. That is 12x (or 1200%) ROI in 300 days. Now I am looking for another 12x in 250 days of course ;-)
If I can pull that off again, I will quit my job in 2020. Now that BTC is looking very promising again, it might go faster than expected.
