Could you please enable PHP currency; TransferWise already supports it. I know lots of Dutch-Filipinos who use TransferWise to support their family back home. Many are already interested in / excited about bunq, but I'm sure TransferWise with PHP integration would really complete the picture.

Actually, this argument holds true for all of the major remittance countries (e.g. India, Pakistan, China, etc), so I would really advise to take a good look at the top currencies. See https://en.wikipedia.org/wiki/Remittance for more info and the top recipient countries.
