Since the best Export of the Philippines is their people (OFW), I can say that adopting cryptocurrency/blockchain technology is really a good idea so OFW's can now transfer money easily without going to any remittances. Philippines is a great place for cryptocurrency only if all people know how to invest, well its hard for the government to do that but this simple steps can become more big in the future.
Maybe you don't understand the basics of economics, The Philippines' citizens is not the only factor for their economic growth, as the government is actually doing a bold move with regards to cryptocurrency, just recently the Philippines particularly the province of Cagayan created
CEZA short for Cagayan Economic Zone Authority which is focused on bringing in foreign investors particularly in the industry of trading, there is a maximum of 25 licenses to be given and a minimum worth of investment of 25 million dollars to be handed of for the first two years. Simply this news tells us if these foreign companies need to earn their investment back they need to persuade Filipinos to invest in their businesses which will be another strategy for them.
