Bitcoin is open source, all right. But the first mover advantage and marketing campaign that it has...well it's insurmountable at this point.
> Problem is that is still centralized
The world doesn't give a damn about that. The only killer app of decentralization as of today is the ability to give people peace of mind that the unit of account they use to store their wealth cannot be tempered with by anybody.
Literally the only application of decentralization was the ability to avoid the ever present threat of money printing because people are scared of inflation and rightfully so. Ever since the stone age people have been diluted by the the central currency authority, it's a fear that is deeply rooted in our brains.
People aren't similarly scared about Paypal or Visa processing their transactions.
Fear is the greatest motivation and fear of inflation is the only thing giving the decentralization thing any market. Everybody , ranging from the supermarket employee to Stanley Druckenmiller...they are all scared as hell about inflation.
And it shows in the marketcap and price of king BTC
BTC gives those 7 billions people a way to express such fears in the market whereas they could only buy Gold, Silver, and Inflation indexed bonds before BTC came about.
