It seems like the FB founder has nothing but positive things to say about blockchain technology.
There are rumours going around that he will release a cryptocurrency for use on WhatsApp, but given the privacy and censorship concerns over FB, I can't see many people going for it.
I think the young man is beginning to see the need or importance of a decentralized global financial system. If Facebook can key into the blockchain technology, it will also be a big plus for them.
