i guess most people in the Crypto World prefer to remain private and anonymous.
From Slackjore who writes the Byteball Wiki:
The thing is you're only giving your details to ONE entity, Jumio. Other entities you give them the fact that you're attested, and whatever else is the minimum they need. It's a bit like PayPal has your credit card info, but when you buy something from a random company they don't get your cc info, just that PayPal attests you're ok. Jumio doesn't even know your Byteball address.
This is Crypto world we don't want to hear the word PayPal here.
PayPal, Visa,Master card ...etc will probably become absolute in a decade or so,that's why visa is already started it's war against Crypto by cancelling all bitcoin visa cards
