You could be wrong: the system comes with a lot of incentives to do the registration. It only takes one person (the initiator) starting it by paying their friend/relative and guiding them through the proces. The new Byteball user receives $20 Byteball and the initiator receives $20 Byteball. Both the initiator and the new Byteball user can seek 2 new users without paying a dime themselves (it is funded by the $20 Byteball received earlier). The circle completes again and this could go on indefinitely.

Giving away $8 to a friend/relative/colleague is a no brainer, especially when pulling someone into crypto tech (at least in my enthusiasm). I wouldn’t feel a loss if I make sure the receiver completes the signup proces. Yes, ‘social pressure applied’ 

I think the biggest challenge for people is:
1. trusting Jumio with giving personal details
2. stating a real use case for 1
3. no Byteball wallet in the Apple iStore

There, I said it  

Apple is the juicy ‘apple’ missing here.

I will surely try to convince a few Android users to give it a try and signup. Any ideas on point 2 are welcome.
