I'm looking for domain hosting. Other than paying in btc (which isn't super obvious on their webpage that they accept it), what do you like about porkbun?

Cool that proton accepts btc for payment. I'm not a big fan of encrypted email unless you always communicate with other proton users. Otherwise, you lose the end to end encryption as soon as it leaves proton servers. If needing to use email to communicate securely, I'd send the plain text email with a PGP encrypted message as the email.
