of course I would avoid the Ethereum network. and currently binancesmartchain is one of the networks with cheap transaction fees compared to ethereum and matic dominates the first rank in the network that I use besides binancesmartchain.Transactions using TRC-20 are expensive in my opinion

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.
because I am not a high-end merchant and only a small trader. so I often use matic which is cheaper than TRC-20, In fact, most of my assets have been transferred to the pollygon network, making it easy for me at all times and bridge any coin I want to trade with transaction fees under $0.01 /MATIC.
