None of the intrinsic aspects of crypto matter if its in a centralized exchange. In the cases of a centralized exchange BTC may as well equal fiat, for it has all of the downsides of fiat alongside the risk of an exit scam/mass theft, and with none of the insurances one may have with a fiat institution.
So, unfortunately, for these “crypto” maximalists, the crypto aspect of their digital currency is just some fun trivia and not something they even bother to leverage.
