What we will start seeing is a type of BIOS fuse like some Android manufacteurs have to see if a phone was rooted before.
SO if you flash your bios, you blow the fuse and they can tell you bios modded it to mine with it.
Because right now as far as I know, its impossible to tell if it was used by mining.
And honestly mining uses less stress than people who overclock/overvolt their GPU inside a computer case without any intake/exhust fans.
microcenter is price gouging. And they wont honor the warranty anymore. I refuse to pay for a card without a warranty. A company should stand by its product. What microcenter is doing should be criminal
