You may already guessed it, one of our main interests at ‘privatekeys.org’ and ‘privatekeys.biz’ is precisely, well, private keys. As mentioned in a previous article of mine, our bitcoin wallets contain the most important piece of information when it comes to our cryptocurrency: the private keys that can unlock the UTXOs that were locked to the corresponding public keys and public key hashes. Please allow me to quote myself once again “Your (private) keys, then your bitcoins. Not your (private) keys, then I’m sorry pal, but not your bitcoins”.
Bitcoin community has some creative ways to protect private keys and the utxos, let me mention them here, and then we will propose a way to better protect our private keys backups.
