The truth is, humans are lazy and used to retrieving lost passwords and atm pin.
Humans are used to sending money to an account they can easily memorize, if the account name is humane readable, the better.
crypto address: "Samuel"
is easier for a user to memorize than crypto address: x008hdgg00880000876548875gdghjf
A crypto user shouldn't become extremely broke and poor when he or she mistakenly sends money to a wrong address.
I shouldn't lose millions of dollars due to a bug in my code (Dao hack)
I should be able to recover my stolen funds if/when I have 100% proof I own them.
All these sounds like or normal centralized banking system, but like it or not, these are the things slowing massive adoption.
I know some of them can't be solved, some can, but
any Blockchain that can bring this or all. Wins
Remember there is currently no Blockchain without flaws
True. I do think, however, that the essence of complex addresses and keys is basically protection and safety. For instance, compared to cryptocurrency wallets, bank accounts have proven to not be as secure. Of course, banks have a tight security system but I do know, hackers would much rather hack 4 digit ATM pins than 20 digit wallet keys. Here in Nigeria, a friend of mine lost a huge bulk of money to online fraudsters. All it really took was his card number. Now he feels more secure storing some of his funds in a cryptocurrency wallet.
Of course, humans are lazy to write down and store wallet keys. But i think hardwork is borne out of necessity. Only when one sees the need to store those keys will he, and if he doesn't, its his folly
