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?
That maybe happen, when people start to think that fiat money system is inappropriate for thr world economy then maybe government will support cryptocurrency more. But government will still more focus on hoarding gold. Gold is special because since long time ago the price still rice and there is no inflation on it.
