I receive a lot of messages from scammers pretending to be interested in selling TRX tokens. Some of them even managed to deceive me for 5-10 USDT. If you are not willing to transfer some portion of the tokens first to confirm ownership of the wallet, then don't even bother messaging me.
Then this will be hard for you to have a client since you are also a newbie and have proven nothing from this forum , though I also doubt that you will be willing to use Escrow as surely most of these transactions are even lower than escrow fees.
just wishing you to have at least legit client that will not scam you by all means.
