Why aren't Miners using them for some of these purposes instead of dumping them after Mining Crypto.
Guess ASICS would become cheap if they can be used for other purposes?
Yes, for other purposes they may become cheap, it all depends how valuable that "purpose" is. GPUs were cheap, yeah? But when it could profit some people a lot in mining, they become very valuable, so can say the same about asics.
And as it was already mentioned, heat is it's best side too. If you live in cold countries or anywhere in winter, you can have good heat system which can save your budget and even give profit.
The core part of ASIC miner consists of only a chip, and it's *almost* useless if you don't use it for the purpose it's created. If you're only thinking of heating with ASICs without any mining, then it'll be super inefficient and cost you a lot of electricity.
ASIC = 1 application, if you don't want it to use it for that particular application, you better throw it away.
Maybe we can open an ASIC museum for old mining ASICs?
