into bither?
cause I have a couple hundred private keys and it will take FOREVER to import
them manually into the bither 'import private key copy paste ' function.
I'm not really familiar with Bither, but you would definitely need to check whether the standards are the same. There are two prevalent standards for HD wallets and mnemonic seed generation, BIP-39 and Electrum compliant schemes. If they are compliant, then yes, you can import the seed and you won't have to copy paste each private key manually.
