In the next 100 years, do you think Governments will create their own cryptocurrency or digital currency that will replace fiat currency, i.e. coins, paper money, the paper dollar, etc.?
If it does happen, will it be like bitcoin or will it still represent gold like how today's money works?
well i do think they will do. Bitcoin has profen that transaction using cryptocurrency is trustable and effective for cross-border country. I do read about rusia going to make their own cryptocurrency, rusia is a big country, i think it would trigger others country to also make their own cryptocurrency.
