Basically, bitcoin has been a peer-to-peer payment system since its inception but looking at the reality so far, how many countries are using it for payment purposes? How many of us are using bitcoin as a payment method or just using it for speculation? We ourselves have never taken any action to promote bitcoin as a global payment network, we are just exploiting it for our own profit. We have no right to criticize anyone.
Yes, the world has not yet reached the point where Bitcoin will become the payment option that will be used throughout the world, but steps are being taken in this direction and are quite significant. Some countries have adopted it as an alternative instrument in conjunction with the standard national currency. And this is already worth something. Not everything is as pessimistic as it seems.
