According to some information published in online newspapers, you can pay most of the costs in this country. Now that the Philippines has installed the first Bitcoin ATM in this country, you can convert Bitcoin into pesos and vice versa. The Philippines is a great country, and this is where we should travel in the future.
Yes, with this exchange wallet if you have Bitcoin to use for travelling in our country you don't need to bother going to banks changing your money or fiat into PHP. Instead, you can just send some BTC to your coins.ph wallet and cash it out on banks and money pickups. It is easier here if most of the tourist spots are accepting Bitcoin, that will be more efficient to tourists that want to spend their BTCs.
Not only that, there are 7-11 kiosk around wherein you can buy bitcoin. But I would agree that if tourist spots started to accept bitcoin, I'm sure it will be more convenient for most tourist. I'm not sure how much is adoption in the country except for coins.ph as major exchanges in the Philippines.
