I am not sure, but probably every market needs another entity to trade to and from.
For example, give stuff x, for stuff y.
Nothing opposes this idea i think, there were ads on different sites about buying with crypto. They just convert ur btc.
Okay, i was looking the countries wich has the higest debt.
Then i found out debt has something to do with inflation.
Japan has highest debt and suprise surprise why ?
Because they have printed too much money now the inflation is eating the money.
And japan have big bitcoin infrastructure of merchants.
Japan is allready bitcoin friendly country.
The next countries are the latin america where the bitcoin is wide used.
I was checking the global countries gbt and debt statistics... so.
In my opinion. The japan currency will be first wich will devalue.
The second will be. Either usa or canada.
And surprice surprice.. you can allready use bitcoins in Usa and Canada.
Both in Canada and usa have huge debt.
Canada money have high inflation also.
So people in canada are prepared to use bitcoins too.
The bitcoin as usual payment method in Europe and Uk are not so common.... so i guess uk and eu currency will survive little bit longer.
But canada and usa will fall down soon.
So i guess people in canada and usa will start using btc then.
