Some time ago I transferred USDC money to my account, through optisim, I was never able to withdraw it since I still don’t understand if I have to have eth in eth or in optisim as such, then I transferred it to my cell phone since I changed computers, but at the same time Transferring my account from the cell phone to the computer again took me to the fact that I only found my eth balance but not my USDC balance, on the computer it does not represent my value but on the cell phone it does, apart from this I would like you to answer me if said balance is lost or what do I have to do to make it appear, also ask them to explain to me in detail about the gas, in what currency I have to have it, if to transform from optisim to eth I have to have an eth balance in eth or in optisim
