The biggest fee is the transfer from Coinbase. The conversion from BTC to Pesos is very small. I once calculated it to be a very low exchange rate but I can't remember how much. But then I always recieve rebates when I pay my internet and buy phone loads. I need to look for another way to fund my Coins.ph account instead of using Coinbase.
