That is correct. It only has a few months left mining ETH or ETC. There may be other ethash coins with a smaller DAG that it could mine after that. If they do exist, they won’t be nearly as profitable.

What is the reason for this?

The E3 only has 4GB of memory and the DAG file will exceed that size shortly. The ETH dag is at 3.76GB today and ETC is at 3.84GB. Once it gets a little closer to 4GB, all 4GB ASICs and GPUs have to mine something else. It looks like Ubiq, Expanse, and Metaverse could still be mined on them.

I have an E3. You can mine ETC and ETH until approx. October 2020, then the DAG will be above the 4GB of the E3. You can continue to mine Expanse, Ether Social and a few others until their DAG reaches the limit. Hope that helps.
