thats their advantage right now. i have only few transactions made via BSC, but i can say, they have pretty low fees, which is actually favourable to crypto traders. at first, i was afraid that i was gonna screw up and sent it to a different network. but if you are careful with your steps, and read what it says, the specific network you are using, it will be all good.
i guess, that's one factor that many people are still hesitant to touch the BSC. afraid that they will make a mistake in sending their funds and end up to wrong network.
