Honestly I really want to know how long can s9 generate a bitcoin....I want a real time not "depends on how you take care of it"tq
Exactly! If you treat your gf in a neat way then she's there for you the way you want and for long period of time. Keeping the miner very cool is first step toward increasing its lifetime period. I'm sure it will be just fine for two to three years if you clean it time to time by halting the mining process and letting it cool down to room temperature. It is also important check the electricity flow through your wires, if it is fluctuating way lot then it might destroy the miner more than expected.
