Based on what I am seeing on my Z9 so far I am not that hopeful at this point it is going to ROI. There must be some secret place everyone else is mining that is getting them great numbers. So far I haven't seen it. Just hoping it will keep earning like this for some time or there is no way to get ROI. Bitmain tossing some crappy coupons at us was an insult.
Ya, the market is taking another dump today....in theory if prices rebound you'll be fine, if not, hey we bought when BTC was ~$9200/btc so consider the real price to be 35% less or about $1350 LOL - assuming you didn't have the btc on hand of course....otherwise prolly not gonna ROI. I'm cool with a hard crash now, get lots of cheap cyrpto over the summer in time for another Dec swing.
