Doller $ is bigger bubble then bitcoin.

Hello dear followers as u know the concept of crypto currency has revolutionaized the world of currency. It has solved so much problems of tranfering and holding the money, there r so many crypto currency coins and tokens but bitcoin emerges as one of the most populer and bigger crypto currency. From the very begining two discources are going on parallel, one are against the btc and second is pro.. the anties are saying bitcoin as bubble on the grounds that it has no back, no responsible authority, no lose seurity and alsome other eligations of such type, for a while if we take is reality and compare US Dollar $ om the same grounds one can easily say $ is bigger threat for world then bitcoin is. Hope so you know that Dollar is not backed by proper gold ratio.. the gold stock that the america has is much smaller then the required so doller is just a piece of paper if today people do not accept is as its written value. If the only americans demand gold from fedrel reserve bank it can not provide them gold of such value.. so dollar is floting in air and any time when people use to ignore it its will nothing instead of a paper. So dear friends if people are agree to accept bitcoin as a currency and they admit its value then it can b act as currency. And it they dont accept not only bitcoin but also doller they both will brust badly... hope fully u understand my point. Plz give your opinion.
