Why always assume the worst and lose gains because of it. You are saying two negative things needs to happen all at the same time.
First, the price of everything should fall, so we are in a bear market, AND then we are going to lose our job at the same time. Isn't that really weird that you want to lose possible gains for a back to back possible bad things?
I do not agree that it's being "prepared", it is being paranoid after a point. If you really want to, 10% of your portfolio could be USDT, and that way you could have some emergency fund.
But, I believe AT LEAST 10x of your emergency fund should be in BTCitcoin.
I think this comes from experience, social class, political/econonomic location. I wasn't even ten when I first saw my parents worrying about money, and this wasn't even close to what happened a decade later in the late 1990s when Asia was thrown into full-blown crisis. I was 17 when that happened. Saw what happened to those who didn't have savings, those who didn't have enough, and my own parents who prepared for the worst.
In societies where the support system is fully reliant on the nuclear family, and then on the extended, you are brought up to prepare for the worst not just for yourself but those within that system. There is no state welfare net to fall into.
So while I'm actually leaning towards your view, I say so having extracted myself from the situation, class and location of my birth. It is easier to take those risks for me, but I comprehend his viewpoint, it having been mine not too long ago.
