I am still working on bagging more the coin I like together with putting money in couple of "solid" masternode coins.
I can do the high ROI coin to hope to get back the investment soon but high ROI mean too risk.
Investment is a long term work, so I always try my best to be patient, not panic when the coin price drop. (look at GIN some day ago, it go to 26k sats for a little moment and now back to 44k sats --> panic selling wont help, and good coin stand).
Beside, I only invest some thousand dollar which is nothing compared to the real investment in real life if you want to have nice return (like house renting, land - need big money to start).
