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?
Many transactions today that uses fiat is already in digital and this is widely used particularly in all wealthy countries. If these government find a valid reason to create their own cryptocurrencies in the future, then they will make it. And if they do, the governments will likely create a cryptocurrency that is similar to their national currencies like cryptodollar, cryptoyen or cryptoeuro and these are all going to be centralized like their fiats.
