Beware of PayPal and other reversible transfer services

[OmegaStarScream]

I heard that we can easily buy crypto through paypal is it true?

Do you mean inside the PayPal app? I believe you can do that yes, although I don't believe that's available worldwide. I also believe "an extra layer of verification" is required before you can withdraw those assets to your personal address as opposed to keeping them inside their app.
