I saw many upcoming projects are offering same kind of ERC 20 token which can get through any Ethereum wallet. It doesn't need any specific wallet. On the other hand hand some crypto companies have unique code and they have specific wallets for their tokens. I am a little confused which kind of token is better. ERC 20 or either the unique one ?
It does not have a unique code, it is just a token that is manage by ethereum wallet blockchain. And the most common part of it, it starts with the address of 0x.
