I just created an account here and was surprised to see GCash available as a payment option. As a digital fiat wallet widely used in our country, I haven't seen this offered at other casinos I've used. While I haven't checked your licensing details yet, I assume that accepting GCash means you must be properly licensed to operate in the Philippines?
I remember that BC.Game claimed in previous posts or community members shared that BC.Game has many mirror sites including one mirror site for Philippines.
They used to have hiring posts for community managers with one for Philippines.
Bcgame currently looking for community managers for the following countries: India, Phillippine, Indonesia, and Vietnam.
There is a user Cointxz and some information and discussion related to GCash.
I try already a direct fiat deposit using gcash payment method for our local currency and it works without any fee. You should use exchange next time if you want to convert your crypto to fiat when you withdraw or just deposit directly using fiat if you don’t want to be charge fee for converting your crypto to fiat.
