Hard Fork wallet blockchain

[yselacreyo3]

I want to take out all the BTC hard fork in the blockchain wallet, but many of the videos show that they sign a message but the option does not sell me in the wallet.

When it comes to a message, it must be signed with a used coin or an unused wallet.

What exactly do you want to do?

Do you want to claim one of the many UTXO forks of bitcoin?
Because bitcoin hasn't had a hard fork.

If so, then just send out your bitcoin to another wallet entirely, then import your seed into a wallet that supports the fork.
