You have to take into account that we constantly have an influx of brand new investors who know very little about what is actually going on, and instead of first researching what exactly it is, they invest first hoping for overnight profits. Some will succeed, but most will pay the price for their negligence and haste, although they could have protected their investment by devoting only a little more time to it.
In light of recent events, I would not call stablecoins a safe way to store value, as these are (mostly) fully centralized coins that can be frozen no matter where they are located. Technically, $1000 in your bank account or home safe is safer than $1000 in a stablecoin that can become unstable or frozen overnight.
Logic makes very little sense to most who can't stand their investment melting away, so they often try to save what can be saved in fear of losing even more. Part of that thinking stems from the fact that people don’t understand what they’ve invested in, but the biggest reason is that most gamble with the money they need, and can’t afford a long-term investment.
@so98nn, you have a typo in the title - you probably meant to write a formula.
