How can crypto help Mark Zuckerberg to fix Facebook?
You want us to do Mark's work for him? What if you're Mark Zuckerberg, you made this bold claim and then realized you don't have any new ideas?!?!
The uses of blockchain are limited only by our imagination to dream up ideas to apply it.
Well i dont think that a deeply centralized concept could ever exist side by side with a decentralized concept. if that happens then we will forget what we ever read and learn abou information technology. anonimity privacy and decentralization are terms far from regulation and such concepts.
So you think Ripple can't exist? It does. It's a centralized entity, business, that provides a solution to decentralize the flow of cross-border transactions.
The only thing that limits your thinking is your will to think!
