Cold knowledge: The gas fee of BTC network is now lower than TRX, less than 1U. ETH chain is also lower than TRX, not to mention BNB chain. However, the TRX chain currently takes away most of the profits from the payment track. This may mainly be due to the first mover advantage brought by the black and gray industry and cross-border trade users, because for a long time, TRX's gas fees were very low, and later they were secretly raised, and everyone was no longer sensitive.
