Please what is correct derivation path??
You do not need to refer to derivation path while importing on a wallet that you are using before. But if you want to know about derivation path which is not what you are asking on this thread, these are the standard derivation paths:
BIP 32: m/0'/0 is the path to HD wallet.
BIP 44: m/44'/0'/0' for legacy addresses (addresses that start from 1)
BIP 49: m/49'/0'/0' for nested segwit addresses (addresses that start from 3)
BIP 84: m/84'/0'/0' for native segwit addresses (addresses that start from bc1q)
BIP 86: m/86'/0'/0' for taproot (addresses that start from bc1p)
But what I most likely guess is that people that are using ImToken wallet are most likely using it for altcoins. For bitcoin, I will recommend you to use wallet like Electrum, Sparrow or Bluewallet.
Assuming you are importing on a different wallet, then you can think of knowing about the derivation path of the addresses that you are using on your old wallet.
