I know that the private key is important. Lose it, I will lose my bitcoin.

I download Bitcoin Core, install it and get my wallet but I don't know how to dump my private key in my wallet.

I search and see a command dumpprivkey address, it can be used but if I have 100 bitcoin addresses and each one have bitcoin, what to do?

Use the command 100 times is not a good idea because with the 100 times I can make mistakes.

Thank you and happy weekend.

If you really want to store all your 100 private keys, you can write a simple script to run the command and send to a file each address and the corresponding PK. I think that can be done.

Or, in a more weird fashion, you can do it manually, like 10 addresses today, 10 addresses tomorrow, etc, but that's a PITA.
