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 do not agree with your assumption, US Dollar, Euro (world currencies), banks, gold, silver debit cards and credit cards are not enemies of bitcoin, bitcoin is one of the digital payment tools that can be used as an alternative among the things you mentioned before.
Although bitcoin has dominated in the future I think US dollars and euros will still be a big part of the economy in the world.
