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??
Why Bitcoin must fight against FIAT? Can you own Bitcoin if you do not use FIAT for trading? It is foolish to have Bitcoin fight them. Bitcoin can exist with them by supporting the same development. We have many ways to eliminate competition and eliminate all doubts because of this.
