Why blockchain.info pays network fees by themselves I'm exploring ways of accepting payments and thinking about blockchain.info 
Receive Payments API.

I can't realise why this service going to pay network fees instead of me. Where the profit? I see only loss.

Can someone explain why they pay fees?
The fees are about 1 cent per transaction - a small price to pay for attracting customers who may later use their paid services.

Offering a service for free to expose a product with paid premium features is a popular online monetization model, also known as "Freemium".
