Its alive, but its not profitable. I don't want to resell my stuff later down the road to some ignorant gamers. I myself am a gamer, who wants a GPU that's been running 100% for who knows how long?
Don't resell if you don't want to. GPUs commonly have 3 year warranties, plenty of time for ROI if you keep up with the trends.
On the other hand I always disclose that my GPUs were used for mining when I sell them. Maybe I'm getting a few bucks less because of that. Never had a single complaint. Running at 100% does not automatically mean something bad.
It doesn't "automatically" mean bad. Sure, Ill give you that. Most of the time its usually 100% stuck next to 5 cards doing the same thing, and depending on the algorithm, strain on the card. I never did buy used electronics, especially computer electronics. Now, I doubt I will ever with.
It's your personal preference and I'm sure you have a good reason for it, but it has nothing to do with mining profitability.
OF course it does. Are you saying you can make a profit off of mining without reselling equipment? If so how? Please, do tell
Now i have a few antminers, and they have soon made a ROI too. So mining is very much alive.
