Well, this could be a good start for Philippines to finally adopt bitcoin as this could bring huge benefits not only to bitcoin users alone, but to the country’s economy as well.
I think that this example is proof that adaptation does not necessarily have to come from the top of the political power, but can be successfully carried out by an individual with a good idea - of course, provided that such things are not prohibited by law. Some may object to the way Bitcoin is accepted on the island, because there is an intermediary who converts BTC into local currency through his app, but due to its volatility, there are rare examples of someone wanting to accept BTC as a direct payment.
If the example of Boracay turns out to be successful, I don't see why other tourist destinations around the world wouldn't try the same concept - after all, Bitcoin is a currency and should be used as such.
