Recently, the BTC ecosystem has been booming.#BTC The gas cost is as high as 100 U, and it is also necessary to incur very high gas fees to move the BTC staked on Merlin back to L1.

There is a path here that may be able to be retrieved at a lower gas cost.

1. Open https://merlinchain.io/unstake and retrieve it back to L2


2. Wait 24 hours for the money to be successfully transferred to AA wallet


3. Use Little Fox to create a wallet (X) to link the Merlin chain (check RPC yourself)
4. Transfer BTC from AA wallet to X wallet


5. Open https://meson.fi cross-chain bridge
6. Select Merlin to BNBChain and transfer a small amount of BNB as Gas
7. Cross-chain BTC from Merlin to BNBChain (about a few minutes)


8. Deposit BTC from BNBChain to Binance

The steps are still quite complicated. I spent a few U to calculate the total fee (it is possible that the network itself is not congested). If there are other better methods, please feel free to tell me.
