Someone told you must buy about $1 Trx Tron on tronlink then you can transfer money so is this correct ?
I can't figure out the exact problem but should be no problem and you can proceed with your transaction.
I also don't know what would be the connection if you buy $1 on Tronlink but shouldn't be that hard to do for a test.
Try it and update us here while I'm trying to figure out the exact problem and some possible solution.
