Monero POW is changing to CryptoNightV7 in about 15 days, so I don't think you can sell this as a monero miner..
Just saying

...but i heard that 10GB asic miners are coming so, even ETH, ETC, ZCASH will be dead for gpu miners
source? I say bs, with a lack of ram supplies (all big companies like nvidia, amd, etc.. have bought all the production for 2 years ahead) , there is no way that asic companies will get hold of it
