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??
The emergence of Bitcoin has created competition between it and Fiat money (and gold). That's normal. Many governments perceive Bitcoin as a competitor to Fiat money, often trying to limit Bitcoin. Therefore, in order to survive, Bitcoin must compete with Fiat money. By the way, history has already seen an example when a better kind of money competed with a less perfect one. For example, when Fiat money was in its infancy, it was forced to compete with gold.
