The main goal of Divi is to make crypto easy. Starting with their easy wallet, where you can send to your friends by simply tapping their username. No more confusing addresses!
It's just an ordinary convenience, although not many coins have implemented such a thing, but so far it's not much of a problem if it's not executed on a coin, because with an address that has been used very often, automatically some numbers in the end can always be remembered by the owner of the wallet.
