Probably not many of you know but there is a tool to easy spot a scam. Its free to use and I’m always using it before entering in a new investment. https://honeypot.is/ this can be used for BSC contracts and looks like this if the token is a scam one
And something like this if its not.
You can also check eth tokens on the fallowing website https://honeypot.is/ethereum.html the principle is the same.
Keep in mind that this way you get a protection only against tokens that have the contract modified so you can’t sell once you buy the token, it can still be a scam.
