I thought GCash only worked within the Philippines ?
It would be great if I could send something like Bitcoin directly into GCash. Is this possible?
Yes, that's possible. I've tested it one time with Dogecoin it's a new Gcash service.
Do you have a Gcash account? You can find the Gcrypto on services then choose Bitcoin then receive, it will shows you the QR code or receiving address send it to someone who are planning to send BTC.
