I have discovered the method of mobile pre-sale, so I will go to the tutorial without further ado. Open the ladder and enter https://presale.mylingo.io/en?utm_source=soc&utm_medium=E1RGD through the dapp of the bitget wallet. Then click on the link wallet and click collect. Wait a few seconds to connect the wallet, then deposit 0.015 ETH as a handling fee, and finally spend 0.0033 ETH as a handling fee. The rest will be returned by the original route, and then you can buy it.
