Why can it be expensive when you use the TRC20 network? I even currently use the TRC20 network only need 1 TRX for each transaction and it's still worth saying cheap because the price of TRX itself is still under $0.1 as well as Matic which costs are also super cheap when compared to BSC.
There are also exceptions in the BSC network, so when withdrawing USD from the Binance in this network, the commission is zero. And if we do not take into account the Ethereum network, where the commission is the highest, then all other alternative blockchains represent competitive transaction prices.
