Paper wallet is a very secured method of storing bitcoins as offline. But its main risky problem is storing without damages. For that, I found a solution;
If you have Printer in your home, Scan your bitcoin paper wallet as JPG image OR PDF format and save it in a New folder.
Next step is convert this folder as .rar OR .zip file with password. Then store in your Memmory card, Pendrive, Memmory card, External Hard Disc OR Personal computer. It never become damaged. Hackers never get any informations from a rar OR zip files.
You can keep copies in multiple devices. Dont store in one device. Because you will lost everything if your hardware damaged. So store 1 copy in your personal computer, 1 copy in Pendrive, 1 copy in Micro SD card, 1 copy in External Hard disc .. etc ...
Remember : You dont connect with Internet. Keep it always as offline.
We can extract these files whenever we want. Then we can take prints if needed.
