It's something which seems crucial to me for reaching mass adoption (in addition to scalabilty of course...).
Already on this forum there is a shitload of people losing their Bitcoins by forgetting passphrases, the private keys, the dat file etc...
So I would like to know what technological solutions could be proposed for this problem.
To make a comparison, a lot of people are forgetting their credit card code (even if it's only 4 digits...) or losing the card and the centralized solution to this is the bank providing new card/code.
Which decentralized solutions to this problems could you think of?
Simple solution for average Joes..
Don't use bitcoin, if you can't remember password, passphrase, private keys or dat file.
Don't use c. card, if you can't remember pin.
Maybe in future we will get finger print, retina scan, face detection etc etc in the bitcoin tech.
