I want to transfer my bitcoin to a paper wallet for long term storage. However, with the risk of fire/theft etc. I'm not comfortable holding it as a paper printout.
So my question (sorry if its too noobie)....why not:
1) create the paper wallet addresses
2) manually write the public and private keys on a piece of paper BUT for the private key, change just one character of the key in a way only I know. For example, increase the 4th character of the key by 1 (so if the 4th character was the number 8, I write it as a 9 on my piece of paper, if it was the capital letter B, I write it as the capital letter C.....you get the idea). So far so good for having a secure paper storage. But what about fire etc...
3) Email the info to my gmail/hotmail account. So I'll always have access to the info as its stored on "the cloud" but is hopefully useless to anyone who hacks my email??
Is there a flaw in my system? Is potentially giving my public address plus 95% of my private key to would-be hackers risky?
Many thanks for your thoughts!
