Yes, this is money of a new generation. Of course, they will not become the main single currency in all countries, but they will be a wonderful additional currency.
You must be dreaming, it's impossible for bitcoin or any crypto currency to become the main currency for all countries.
As long as there are people who govern this world, the centralized world will prevail over the decentralized.
I am trying to wrap my head around this thought as well.
If bitcoin can become a mainstream currency.
In order to do so, the price fluctuations MUST stabilize.
This means, that bitcoin cannot be hoarded by a handful of people or groups but must be more evenly distributed.
For example...say every person in the world had some fraction of bitcoin, this would lead to the ultimate stability.
One of the first steps in accomplishing this is for countries to recognize bitcoin, like japan. Once people can start to buy goods and services with btc on a larger scale, it will normalize the pricing.
The fact that some shadowy figure named satoshi nakamoto and chinese miners hoard tons of currency is a huge negative to bitcoins possible mainstream adoption.
