That's the question I wanna know the answer well, but the problem is that no one can give the exact answer for this matter.
And in my opinion its platform was actually dubious, I hate to say that but what can I do its the fact.
This thing must resolve the ERC20 in terms of their high charge fee.
This is not a dubious thing but basically the ETH network fee is higher than the BCS network.
Maybe because of the high price of ETH, there was a change in delivery gas.
Let's see first before the price of ETH is expensive as it is now, ETH is cheap and gas is cheap, right.
I don't think there is a solution to the high shipping costs on the ERC20 network unless the ETH price drops again like last year.
