After 5 years of stirling service and a lot of modifications I'm retiring my rig of 8 x 1070's. My remaining 2 rigs, each with 8 x 1070ti's are running at around break even so will keep them spinning a few more months, at least until the Australian winter is over.
The question now is what to do with them? The 1070's are old cards now and I can't imagine there is much of a market for them especially considering their mining history. (Though one could argue they are thoroughly tested!). I doubt it would be worth the hassle of listing them on ebay. But I can't yet bring myself to throw away perfectly good cards. So I will probably store them for 10 years and then throw them away!
What do you do with old mining cards that are no longer profitable and unlikely to ever be profitable again?
If you store these graphics cards for 5 years, then it's tantamount to throwing them away.
When mining becomes unprofitable, be sure to sell these video cards to buy cryptocurrency. When the price of the cryptocurrency rises, you will buy new cards. And if the price of cryptocurrency does not rise, then you still wanted to throw away video cards.
