"How to detect scam token on Binance Smart Chain"
If it's on Binance Smart Chain, it's a scam.
IMO, I think it was a very shallow observation, I dont know if you really mean it or it's just a sarcastic notion but all I can say is not all projects on Binance Smart Chain are scams many are still good, and performing well. and one more thing scammers are not settled on a specific blockchain they are everywhere even in Ethereum there are many scammers too so it's very unwise to tell that if it was on BSC it's a scam.
