When people says they never invest, it's a bullshit, they never invest means they keep all their asset in cash, fiat currency of the country. Which mean they are all in in the fiat, don't forget the central bank can keep printing money that devaluating their asset on hand.

In this situation, why still keep all the cash / fiat on hand? And of course, I no longer pay attention to the stock, bond market since I joined the crypto world.

I only keep some of cash / fiat for emergency, say, need to go hospital, paying a super expensive bill. Reserve some cash to buy my wife a new phone (oh fuck, the iphone 15 came out already)
