Advice on ERC 20 please

Hi,

This might be a bit of a stupid question as I’m new to crypto but if someone could please help.

I bought £100 worth of thorchain through uniswap and it’s in my Coinbase wallet.

Instead of it buying the coin, it bought the ERC 20 token and I’m not sure on the difference between these.

Do I need to transfer the token to the coin to reap the benefits if the coin goes up in value?

Or if I sell the token will it just reflect the current coin price regardless?

If I need to transfer to the coin does anyone know how?

If someone could please assist it would be much appreciated.
