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.
Can I send BTC or any other crypto to a GCash recipient without having GCash myself? ( ie. from a DEX )
I am not filipino by the way, it seems you need to get verified with a filipino ID to get GCash
