You bought three Antminers and you don't even know what you can do with them? LOL.
I'm using them for BTC, but I just wanted to know if I can use them for ETH too.
Hi,
You can use them to mine any coin that supports the SHA256 algorithm, and only that.
Do a search on coins with that algorithm or just go to
https://whattomine.com/asic and check the coins/profit there.
No ETH mining for S7 thought...
