Thanks for the tips OP but I think that method is only effective at preventing yourself from being a victim of the clipboard attack. Also, that method will not make you 100% safe from that kind of attack because the hacker can try to just brute force the character you have edited since he got a clue on how your private key is structured(since you will only edit 1 character). Instead of editing only 1 character, I think editing 5 characters at least will make it harder for the hacker to access your wallet.
Thanks, mate. I think it will be more hard for the hacker and we will be safer.
In the case of the private key it's best to write it on a sheet of paper, or in two if possible. If not, you will run the risk of forgetting the digits or letters that you have changed and in addition you will still be at risk of being hacked and that the attacker discover your trick, especially if you only change one or more consecutive characters at the start or at the end of the private key.
But I think storing it in memory that is not accessible to the network or can be called offline will be safe because hackers do not have network access to retrieve it, indeed the main mistake is that each of us does not pay attention to the original site and does not pay attention to public connections, it is very risky to use it arbitrarily, so pay attention to its own level of security if after all is lost, everyone doesn't want to know.
