Lets assume i have a btc wallet with no public key inside my core wallet, now i import this
one inside blockchain.com wallet, there i have the funds now, i will instantly sell these btc
coins for usd, and send my coins out there, said it, this is the way i assume all, keyfinders succes rate.

there now you have you have your coins on one of your own wallets, but now, not the forks??
i guess, or you have to do this inside the blockchain instantly with multiple windows open, but blockchain.com
prehibits this, one browser window allowed open logged in at the same time, the same you can do with the
bit of forks, but guessing the valuable btc should be enough to have there if imported,

is this not tested before, haha there this public key will not leave from your possession, untill you sell the coins
inside blockchain wallet, should be fine. i guess
