I think this need to be moved on our local board to create more awareness there but it's relevant as well here, maybe make a new thread if this one isn't moved. Luckily not into gambling transactions anymore that frequently but even before that I do it even on weekly or biweekly basis I try to avoid this silly mistake as I know my account will be at risk I try to do so.
What I did way back was sending the coins to a mixer or to an exchange before proceeding to the actual gambling site or my own address, it's way more safe. Not that a regular user of coins.ph these days and I think they really are now into strict regulations, not a bad thing that they make it a prompt before a user does.
