I have a small mining rig, has been operating more than a year. But lately, I have been starting to increase my holdings in POS coins (BEAN, DMD, ETH) since late 2017. Knowing i can't keep enjoying this income from POW / mining operation. Nicehash hack, DASH ASiC , Monero ASiC has thought us why. I'm sure i will be much much happier when I hold POS Coins, especially those that will keep gaining value over time.
