Is possible to receive usdt trc20 in TON wallet without having funds in TON wallet?

No, it is not possible to receive USDT TRC20 in a TON wallet without having funds in the TON wallet. The reason is that receiving USDT TRC20 in a TON wallet implies that you are transferring USDT from one wallet to another, and you need to have funds in the TON wallet to receive the transfer.
