I suggest to save these tokens maybe If we pass the bull season, these coins' prices will increase and you make profits from these coins. In our wallet, these coins are harmless. I have many coins and most of them scams but I save it and will this is best way.
Wishful thinking. If bull season came, its the tokens that can potentially be profitable are the ones that will start the bulls, not the shitcoins. Though it won't hurt if those tokens just stay on your wallet, it may be clean if you can send it to an address whichever address that may be or simply to the 0x000000.. to burn it.
Me, I just keep it in my wallet, especially an ERC20 token. I made these worthless tokens as a number of experiences where I was unlucky and my work is not valued at all. After all, I like to see there are many types of tokens that I have in one eth address.
