Btw I mind it too hahah. Backup methods will need a lot of changes in the technology itself. This is a trustless system, which needs the intervention of the person holding bitcoins. No one else should be involved. The hardest part of crypto currency is listing of pin and crypto wallet information. So better to take precautions at owns end, probably make a process documentation for recovery and put it in your legal will. I will advice people to at least share their secret pin with their wife or child to avoid a big mistake when someone dies ,so that your crypto currency will not be a wast to your family when you die.
