I am using coins.ph for quite a while now but I haven't tried to use my address on a gambling site. Since there is binance and I trusted the platform, I preferred using it for convenience.
As far as I know Binance also restricted, you can’t deposit any crypto that are coming from your gambling activities better to check the ToS of Binance now to avoid any inconvenience. With my gambling activities, I always use Electrum for my withdrawals and coinsph is only for withdrawals in peso, this is way more safe I believe.
