I have a small mining rig, has been operating more than a year. But as the situation develop right now. I have been starting to increase my holdings in POS coins 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. As mentioned above, POS makes any attack attempts riskier and that makes the holders happier. :D
