That's right, actually there are too many shitcoins on erc20. I was really depressed because I had spent a long time working on campaigns and what I got was shitcoins. Creating fraudulent money codes is easy on the ethereum blockchain through projects with crazy ideas but still approved. Then the project is not successful, the token does not go up the exchange and that leads to the scam. Therefore, I hope that shitcoins will gradually decrease, which helps bounty hunters to continue their work.
