Once upon a time every erc20 token was a scam, that was the way of newbies that came into crypto space in 2018 ( bear market ) they probably make one or two investments that doesn't do so well as they hoped for, I wouldn't have made my 12,000$ in 2021 if I believed that all BSC projects are scam...learn to do research first before saying such statement.
It means that you have learned a lot about everything in the past and also in the present because the ERC-20 token in 2018 is a trash token which will eventually become a scam and the BSC token whose owner is not clear will also become a scam in the end so it is actually already almost similar to the past although you are late to realize it now.
