I know how strict Coins.ph when you are sending Crypto but not when you are receiving, so I use Abra or peer to peer when sending Crypto to a gambling site, but I have done it only twice, Coins.ph is very strict and they very strict in where you are sending your coins even if it is a small amount, so it's better to limit your outgoing transaction than incoming.
Thats true, coins.ph are more strict for outgoing transaction especially if you're sending to a non coins.ph account. Well its understandable if they are more strict now, and that is to monitor any unlawful activity. So if you gamble frequently, use another wallet instead and just use coins.ph to cash out.
