What you’re holding now with ETH on BSC is technically WETH. You’re holding tokens that are pegged to ETH price. In terms of price action, it is going to move like ETH. So if all you want to do is to be exposed to the price action of ETH, you don’t have to do much else as keeping your tokens on a sidechain is a cheap way of retaining ownership of those tokens. Cheap because BSC gas fees are fractions of what you see on Ethereum mainnet.
If you want to go to the Ethereum mainnet, you will need to pay those Ethereum gas fees no matter what. Tbf, the withdrawal fee to Ethereum mainnet you pay on Binance isn’t that bad. If you’re really trying to penny pinch, you can use FTX, as FTX’s ETH network withdrawal fees are much much lower than Binance’s.
To do anything on the BSC network, you’ll need to buy BNB on Binance and send it to your wallet. BNB is the gas token of BSC, without it you can’t make any transactions on BSC. Once those BNB has arrived in your BSC wallet, you should be able to send those ETH back to Binance via the BSC/BEP20 network. Be sure to double check the networks you’re sending/receiving to/from. Or, you can dabble in a bit of defi since you’re already on BSC.
