It needs more time that it will happened. Adopting bitcoin needs first to be accepted wholely by the country such as the government. For now there are companies and bayad center who accepts bitcoin payment which is a sign that sooner or later bitcoin will be accepted in the Philippines.
The government already accept it. Small merchants in makati and bitcoin ATM was established also in makati. Government will regulate by forming anti money laundering team to monitor all transactions and allowing only companies that given a license to operate in the philippines. This ensures the are not just adopting it but to protect investors and users. Hopefully they will start giving a salary in the form of bitcoin so that bitcoin will spread to the whole country.
