The ROI of BTC is just insane! Best investment to beat inflation...
That sure is some interesting data, but let's not get over ourselves and automatically conclude that bitcoin would be the best investment to "beat" inflation. If you're in some third world country, sure. But if were talking like bigger countries like the united states, we really don't know. If the US went through hyperinflation for instance, we won't know for sure if people would be moving their money to bitcoin(which I personally doubt), or if people would be selling their bitcoin to have money to spend on things(which I personally think is the more likely scenario).
In the end, no one knows, and only time will tell.
To me, on the other hand, it seems only logical that in an event of rapid devaluation those that have savings will be interested to preserve them by selling fiat for precious metals and, very possibly, Bitcoin. You're saying that it's a good investment in a third-world country but not in a developed one, but it seems to me that the opposite is also reasonable. Think of it this way: people from the third world are more likely to have fewer savings and focus on survival. Thus, they'd need the money that can buy them things, even if this money is rapidly losing value. They cannot afford to make savings or whatever if the question is whether they have enough to buy food for today. In a prosperous country that is suddenly hit by hyperinflation, on the other hand, many people are interested not in survival but in remaining rich. So selling BTC to buy the money that loses value does not make sense to them, whereas selling fiat from their wealthy bank accounts for Bitcoin seems like a good choice.
