Digital documents, even after encrypted....can be decrypted. Some people even reported here that they encrypted the file with the private

key and then posted it on cloud storage. This is stupid, because most online activities are logged and monitored. You print the paper wallet,

and then laminate it, to keep it dry. Most digital media fail after a few years... so I hope you burnt some copies onto some CD's or DVD's {not

that they last any longer, but still better than HDD's and memory sticks. }
