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?
So imagine this thing is happening now. All countries have their altcoin counterpart of their currency like dollar, pounds, peso etc. Does this replace bitcoin and become obsolete? No. Well in fact i think it can make bitcoin grow more. People will obviously have two coins in their wallet that time. Their local currency and bitcoin. Instead of converting into another currency, and affects exchange rates, they will go to bitcoin and use it as their transaction worldwide.
