I still don’t explore this email because gmail is my first email when I started exploring crypto casino online. But I do encounter some friend that suggest this email instead of gmail.
I can attest that proton is a good email provider and they're valuing their users privacy and it's proven already.
My only worries is all my casino account is already connected to a gmail account. Is it possible to transfer email to protonmail?
I do agree that I received a lot of spams on my gmail even if my email was created only for single casino account.
If it's possible to change email to accounts, then you should do it.
But if it's not, then stay to the gmail that you're using on them in the likes of your betfury account.
