If you are not base on US, then you won't see this option for now.
That's why it's a bit confusing because I keep seeing news and articles out there about PayPal, where you can able to send and receive, but on my own PayPal account, even though I have funds, I don't see other options to choose crypto; I only have two options: our local currency and USD.
Now I see that this is only available to US citizens? I dig deep research, and it looks like it also has support in the UK and Luxembourg. But in Luxembourg it is only for selected users.
According to PayPal, they are trying to expand their service for crypto worldwide, but because of international regulations, the process is very slow. But this was 2 years ago and until now they don't added more country to support crypto.
