I built an ERC-20 token named Moontrail and the symbol is the same that Metal (MTL) I am afraid when listing on exchanges and coinmarketcap. Should I leave it or create another one?
You can have the same name and symbol, but it's not recommended, especially if you want to list your token. I highly recommend you come up with a different name and symbol to avoid confusion
From a technical point of view there can be multiple ERC20 tokens with the same symbol.
It's going to hurt your brand for sure. This is a decision you have to make.
