while if you will sell your 1 BTC in coins.ph, you can only sell it at 205,989, so if we compare the rates, you can save Php 5,011 for that transaction.
Also, be aware that there is a fee when sending paypal from different countries, you can have it free if PHP to PHP but if PHP to US or other countries and vice versa, there's around $1-5 transaction fee, but that's negligible, you can still save a lot of money.
The main question now is finding a reliable exchange platform or person that you can sell your BTC for paypal funds. We all know the nature of paypal a reversible payment processor. so exchanging your BTC to PP is a high risk transaction not unless you find someone that is real legit paypal exchanger.
True, If the person you tried to trade file a dispute against you then for all you know you can't bring your BTC back to you. I think that if PayPal finds out you trade funds btc to paypal most likely the person with paypal dispute win.
