@fedup Your private key works same as your seed phrase to import your tokens.
Only difference is seed phrase imports a multi coin wallet which means you have basically all tokens under that (BTC, ETH, LTC, ERC tokens, BEP20 tokens, etc.) while private key imports just for a particular chain so your private key for BTC may be different from the private key for ETH and likewise for any other token on another chain.
