"How to detect scam token on Binance Smart Chain"
If it's on Binance Smart Chain, it's a scam.
It doesn't mean all of scam coins are developed by using Binance Smart Chain, but it’s true that right now i see most of SCAM coins in BSC if will compare with Ethereum blockchain although BSC is decentralized. And i think also it can be, scammers target BSC because here it's easy to create a new token. Scam coins existence in every blockchain comparatively low instead of BSC.
Scammers move were the money is, back then when ethereum had almost a monopoly compared to other smart contract coins most of the scams concentrated on the ethereum network, and this gave ethereum a bad reputation among some investors as a facilitator for those scammers.
But now that there is a huge level of competition in that market and the binance chain is extremely popular then it is understandable that now a great deal of the scammers have moved on and now they are trying to scam people in all kind of platforms.
