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?
I would think they will yes.
Unfortunately a lot of banks and big government and big BS will happen.... By BS I mean stuff like central banking and controlling the coins and all that crap. Likely wouldn't be open source either and they would have the right to censor and ban people from using it(which is scary!!)
