I still don't understand, by whom it will be broken, I also wrote software and I am searching randomly.
What should we do to transfer, add the private key in online wallets and go to the transfer form, use phone apps, which wallet software should we use to withdraw the balance, or write a program for the Bitcoin transfer form or Should we add its in Bitcoin core???
If you initiate a transaction you will reveal the public key. Since it belongs to a 66-bit public key, you can quickly find the private address with kangaroo or bsgs because you know the range and it is "narrow". Then you will start your transaction and generate a double expense. To win you will "bid" a higher transaction fee to get more confirmations faster.
If there is any mistake in this, someone correct me.
