> someone created facebook make people believe that it worths billions

Facebook make billions on ads, you don't have to make people believe when you are making wads of cash. And even when Facebook was new the business model was proven to be valuable by Myspace and the many other similar sites making lots of money on ads.

So your post here just strengthens my argument, the fact that you don't see the difference between the two just proves that you have turned off your own sanity checker.

Edit: What we are seeing now is similar to the investment craze in IT before the dotcom bubble. No sanity there, people just invested without thinking. I'll believe in crypto when people starts to think before investing in it.

I think you didn't get the point .. making crypto the default banking system is paradigm shift and efficient paradigmal application. I gave the facebook example because the economic approach which offers that supply and demand is right tools to decide whats good for humanity is simply not accurate.
