Is it possible to mine this coin with only XMrig?
Without need to use the miner made by Epic?

I feel safer to use a stable and reliable miner


And which pool to use? The best one, the most simple to use?
I see that some user have problems to withdraw coins from this pool: https://www.reddit.com/r/epiccash/comments/eikzrp/move_epic_from_iceminingca_to_epic_cash_wallet/

Edit:
Wow, I tried to use the wallet and the miner, and it's very complicated for me 
I will give up
