Chris Larsen, Ripple co-founder, is estimated $59.9 billion on paper Due to possesion of 5.19 billion Ripples and 17% stake in Ripple he is more richer, than Google founders. Recent rising of Ripple (I bought some) has pumped his fortune in a very positive way 😁.
There sure will be more billionairs in cryptospace in 2018. Wish one of them would be me and you :)
