Bitcoin is trying to eliminate US Dollar, Euro (world currencies), banks, gold, silver, anti-government, debit cards and credit cards, anti-tax
How will Bitcoin survive the many enemies it has created by declaring itself a revolution in payment system and decentralization??
I don't think bitcoin is trying to eliminate any of the things mentioned above. I think the main purpose of bitcoin is to be a global currency that can be used by anyone around the world, and not to compete and eliminate each countries fiat currencies. Although it is still not that widely used as a currency, still I can see that it is also considered as another way of payment and is used in transactions just like credit cards and debit cards of banks.
