I am managing a few rigs for some of my colleagues and everything is going well with Phoenix miner mining Ethereum.However most of them have 4Gb cards while I see the epoch right now is 3.44Gb and I think won’t be long before 4Gb cards stop mining.Except that switching to Monero,is there any other viable option for these cards or should I consider them done?
The only option you have left is Monero, its the second most profitable coin to mine presently as per whattomine mining result, Monero changed their algorithm weeks back and it did lower the difficulty and transfer fee as well, you should give Monero a try
