This is how many Bitcoin people in here are arguing:
I saw some people buy a can of Coca Cola for 2000$ just a month a ago.
Now I can buy a can of Coca-Cola for only 500$, it is cheap!!
Bitcoin is not cheap at 6000$. It is make-believe toy money with no real value apart from some novelty value for people who like to have cryptos for fun.
This has always been the argument why Bitcoin is hardly becoming the currency that the founder Satoshi Nakamoto originally envisioned. The price fluctuation of Bitcoin has been hampering its full function as a currency. Your .00001000 worth of Bitcoin might get you a piece of hamburger this very moment but in a couple of hours, it might not even give you a piece of bread. But I believe that once Bitcoin becomes the primary currency of the world, there will be a more or less stable price. Well, that might be begging the question, but Bitcoin is actually being used as a currency right now.
