If the entire world is bankrupt, how will the price of Bitcoin go up since everyone is too poor to afford any investment?
They will end with something so precious that nobody affords it and they will have to sell it for pennies.
Let's not even count the 2 million that will have to go back and end all the remittance flow into the country.
Although it is a difficult scenario to determine, I think that in these cases the only one that can take value would be gold, Bitcoin in this case would function as a possible store of value, if FIAT money explodes in its big bubble, BTC would not lose its value, that is, their intrinsic value would be maintained, which actually if I have a big doubt is if they could make a pair of BTC / Gold, if both represent money.
Of course, this enters into a purely speculative topic, but when a world crash arises, FIAT money is the one that must recover, plus the value of BTC not, because it would remain and perhaps rise, it would be somewhat complicated.
