Seeing as the economy is intertwined, overtaking a position on this chart would have to be a combination of numerous factors, not just inflation on some currencies (and inflation is not guaranteed nor is it as simple as just printing money).
Inflation is guaranteed, that is how it has been from the beginning of fiat creation.
I wouldn't bet on BTC hitting any top spot anytime soon, I'd be surprised if it overtook the Franc.
Do not always believe in the articles you always see online, some are just misinformation. 1 BTC is equals to 1 BTC, that marketcap above is the circulatory supply if bitcoin, bitcoin total supply is 21 million BTC. How will bitcoin move higher unless it is compared in fiat value and not in BTC value.
I'm not sure how accurate this is either. Let's see if someone with more knowledge can enlighten us. In my case I think it is not enough to add the current supply, assuming it is accurate, you also have to take into account the strength of the currency, and I think this is done by comparing it with a reference, as I think they do in the case of this website regarding Bitcoin.
The information will not have the correct representation of bitcoin value. You are getting it too.
