I think the days of home mining and small mining pools are coming to an end. If you cannot add hashing power to match difficulty you are just spinning your wheels. The mining manufacturers need to produce a 20THs miner at 1500w that is affordable for us to buy. This latest round from Ant and Canaan is just a money grab taking advantage of people looking for an answer. If things keep going at the rate they are now my 55THs operation will not be profitable after June 2018. If BTC goes back to $20K it will give me a few more months. If China bans mining the overpriced S9 will be worthless on the resale market. We went from 72 blocks in June to 8 in January you do the math.
Everyone with free electricity mine on! I am searching for answers if anyone has a plan.
I have been thinking about this same thing for the last couple of months as well. I'm in an even worse place that you with my 27TH hashpower and really not able to add more without a decent investment. With the difficulty increasing as fast as it is and the BTC value leveling off a bit I'll be done mining in the next few months. The question I'm wrestling with now is whether to stop now and sell my miners at a good price on eBay or wait until later this spring to do it and take a chance that I can't get as much for the miners. Either way, I'm a bit sad about it since I've only been mining for about a year and have enjoyed it a lot. I just don't see this being profitable for a small time miner for much longer. I'm wonder what others in our situation are thinking.
