For me as I came late to the "crypto" game at the beginning of 2019, I think I went full Bitcoin one year and a half later, only after I realized that the ethos of Eth (the only other coin I ever owned), was far from what I came in originally. No cypherpunk, no libertarinism, no freedom here. Just pump, dump and silly used cases who could maybe and only improve the world at the margin...or not at all.
If the messenger is rotten, you can be sure that his message is too. You can see this in every aspect of your life. Climate change hysteria, covid panic, wokism...every time the agenda is held by socialists/marxists/anticapitalists ideologists. The ethos of the spokenperson and communty is largely enough to raise a big red flag without even studying the subject in depth...
