The problem is not only in whether or not the so-called stablecoins are backed by anything, but also in the fact that most of them are centralized to such an extent that their issuers can freeze them at any time. All those who use stablecoins for any reason are therefore always exposed to these risks - so the question arises whether it makes more sense to trust fiat currencies of central banks or so-called stablecoins, which are practically the same thing issued by private companies.
The volatility of Bitcoin can be a problem for those who invest in the short term and are also prone to panic - but if you are in Bitcoin for the long term, then this volatility can only be an advantage, not a disadvantage.
