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 them. But he wants to prove that they can all function as one money. This does not mean it will destroy them, but it must be acknowledged that it is a strong opponent.
