I do not believe that in the Philippines will officially accept bitcoin. In this country, a highly developed drug. It is possible to increase the volume of transactions in bitcoin is primarily with what the drug dealers are easier to trade for bitcoins. For the economy of the backward countries bitcoin will not bring any benefit.
I understand your point. more than understand, it is a valid point. But here's a thought:
Mexico is also a drug-flooded country, much worse than the Philippines, even. Yet, the flow of Bitcoin was able to increase the GDP of the country. Venezuela, is among the list, too. But digital currency helped the locals survive the very high inflation effects of their country.
There will always be ways for people to use these things for crimes, but we need to take note that modern fintech is able to track down these things.
A regulatory framework is the most important key factor here. That is why I commend the Central Bank of the Philippines for having been able to quickly initiate the AML and the KYC to these local exchanges.
