No it isn't.
It's still gold and fiat.
But it would be because bitcoin is new.
It has been popular nowadays
and there are lots of supporters
So someday it would have the potential to become strong.
Thats right dude, bitcoin can not be said as a strong currency, while bitcoin is still in the stage of growing and growing. I think fiat is much stronger than bitcoin. Btw I think gold is not included in the currency
There is no doubt that fiat currencies is stronger than bitcoin because they are already in the world since their country declared the use of it while bitcoin is just strong and it will get stronger as the days,weeks,months and years will pass because it will have a lot of improvement through the time that will pass and that will make bitcoin one of the strongest currency after 10 years.
