BTC balance is zero after importing other wallets' mnemonic into imToken
When importing BTC wallet mnemonic into imToken, the default address type is SegWit and the path is m/49'/0'/0'.

If you import a mnemonic generated by other wallets into imToken and find that the BTC address changes and the balance shows zero, this may be due to a discrepancy in the address type and path.

Please ask the customer service of the other wallet about their address type and path, and then click "Advanced" when importing mnemonic to imToken, and enter the corresponding address type and path.
