The Philippines major cities have many options for bill payments, but not in smaller towns.
Those that are 'stand alone" outlets/services normally work on a small fee from the provider and zero fee from the customer and you need to go there using transport and frequently queue.
I can guess that ninja has a regular payment service provider in the background ...bitcoin is remitted to Ninja who exchanges it to fiat at the current local rate 1% and then pays your bill for you.
If your busy/at work /want to pay from home or cellphone/ avoid queues (agoraphobic )/lazy or the cost of traveling to a payment center is almost = to or more than the P30 + 1% cost of exchange to fiat... this is a great option. To put in context it costs a minimum of P30 to go and return from anywhere and normally much higher than that.
Very nice and innovative and groundbreaking...Good luck
