I have cgminer still running on my single solo mining blockeruptor. I still have a bunch of old miners in my forgotten altcoins folder, like QTminer.
I still want a 3080 but to be honest the new AMD gpus are going to be awesome. I hope. The 5700 is discontinued, 5700XT is too expensive now and the 3080 is impossible to actually buy today. That leaves us with only big navis in a month. I shall wait. Also if u use nicehash for mining ETH depending on your setup, sometimes it switches to crazy fast dag coins and that can cause your rigs to experience errors/reboot.
Yes this is actually why I stopped mining any type of DaggerHashimoto type of coins on Nicehash. Same with mining any Dagger altcoins with Claymore because I could never for the life of me find a way to make the DAG switch stable so it doesn't crash a rig.
Even back in 2016 when I mined Ethereum using ethminer (miner included with ethereum wallet) every 5 days all my rigs would crash during the new DAG. You could see this live because if you went to ethstats you would see that the hashrate immediately drops after a new DAG.
Then when Claymore came out it was fixed whenever a new DAG came out, but you couldn't mine any alt dagger coins with Claymore because the dev fee would switch back to ETH. The constant switching back and forth eventually crashed a GPU or two.
