How to determine that a coin cannot be sold under a smart contract?

Question

Cryptocurrency

Hello, I decided to buy a coin from one nft marketplace, which should be released tomorrow, but suddenly I remembered about cases of scam using such coins. As far as I know, in the smart contract itself, it is possible to prescribe the absence of the function of selling a coin. Please tell me how and where to read this information.

Here is a link to BscScan coins - https://bscscan.com/address/0x3d0E22387DdfE75D1AEa... .
There is also a smart contract itself. I would be very grateful if someone could explain how this is done using this coin as an example.
