That's actually a great option since it's safe. However, there are already several casinos accessible in the Philippines that accept GCash as a payment method. Some platforms I'm familiar with include 1xBet (though it has a questionable reputation in this forum) and BK8. This availability isn't really surprising, perhaps many of us just haven't explored enough options yet.
Did you miss remembered between 1xBit and 1xBet?
I intended to search for a topic to support your information, and found this.
[WARNING] Beware of 1xBit casino, investors from Telegram, and Youtube scams!Then I am surprised that it is about 1xBit, not 1xBet, and thought you was wrong, but checking further, I got something interesting.
Cleobet: Another betb2b (1xbet/1xbit) clone - Flag to be supported. They made many scam clone sites time to time, and 1xBit as well as 1xBet are created by a same scammer team.
I believe these platforms are interconnected, and I've actually tested their casino myself despite their questionable reputation here. They do offer local payment options like GCash, which is why I mentioned them as examples. Though I'm pretty sure most of you would avoid them anyway.
On a positive note, it's great to see legitimate sportsbooks now catering to Filipino players. I've also noticed several PH-based vloggers actively promoting BC.Game, which seems to be gaining traction locally.
