as far as i can see.. phililppines has not regulated and has no laws in place for bitcoin.
does this mean a philippino can currently .. eg. cash in a large amount of btc on an exchange.. and withdraw back to PHP bank account and pay 0% tax ?
I don't know what you mean here bro, but as far as I know, up to this days there is no law that regulates bitcoin in the Philippines..
Though you can withdraw tons of money thru a local exchange here in the Philippines, you are not safe in the eyes of the law...the local exchange here requires valid government ID to raise your cashout limit..It means, you can still be traced..
I just don't know what was the permit given to this local exchange or what they apply for, either for a remittance or really for a bitcoin..
But about the law, there is a cybercrime law here in the Philippines..
