For real, this guy is making a point, but the issue is that people do not look at it from the economics perspective but from the investment perspective that can only enrich some sectional individuals (if it works because there are risks involved) but not a country. Can Bitcoin be used to adjust a country's inflation? No. Can it be reasonably used to secure a national reserve? No.

Trump is just a desperate person who is using people's weakness against them. I wonder how a country would feel if it had a $100B domicile in Bitcoin in its reserve and Bitcoin dropped significantly as it does during the bearish season. Such an amount could have devalued to $25B in some situations if we consider the past record to judge. Now tell me, do you think the National Reserve is a joke? Think of it, some central banks are using the reserve to adjust their FX deficit most time where they could remove about $2B at times for the national economic stability.

How would they feel if they were selling their Bitcoin at a cheap price when they bought it expensive and they couldn't wait because the matter is of pressing national need? These are just a few of many reasons to discourage any economist from going in the way of Trump and Bitcoin bigots. Notwithstanding, Bitcoin still has its usefulness aside from what Paul Krugman claimed.
