For example, because accounts are designated by simple user names rather than long and impossible-to-remember numbers and letters, the potential for simple e-commerce marketplaces are HUGE here.

I've just imagined a future where people will create fake accounts with usernames very similar to real accounts, hoping someone will mistype the username or their friend or relative or whatever, and send the money to them! lol!

I bet tons of people started here and NOW also are invested in other coins.

You're looking at one.
