I tried to send XRP to one of the gambling sites I'm using, but I was prompted with this message.
^ Wait, is this a custodial wallet right?
Any custodial wallet we use must read the TOS before using it because most likely they are followed by local government jurisdiction which is against gambling activities. There will be a big problem if you will not read carefully the term of use. However, this is a great warning to us even though those who are not Filipino are using local crypto wallets. We know that our government is very strict on money laundering and those regulated wallets should be avoided. If I were you, BTC mixer service is the best for you before you will send it to your custodial wallet.
Its an exchange if I am not wrong so there is no surprise that they are restricting incoming funds from a gambling site since their government doesn't allow it, using mixer can be an option but its not a much reliable one so anyone wants deposit funds to coin.ph have to mix their coins everytime before depositing to avoid the account termination.
