user44978: I'm new on coinbase.com, and it looks like (surprisingly), when I order a 0.1 bitcoin transfer to somebody's address, then if I look at the transaction on blockchain.info

Network fees of 0.224 E-3 BTC are paid 


Source address pays 0.1 + fees + change
Another coinbase related address gets the change
recipient gets 0.1

The recipient gets the full 0.1 BTC (they confirmed)
My account goes down of only 0.1 BTC

Who pays the network fees? Coinbase on their own money (sounds very surprising)?

user44978: Yes, they do. Apparently they have a big enough cashflow and a good enough optimization algorithm to make this worth for them.
More info on the way they do it here

user47820: At the time of the question being posted, Coinbase was paying your transfer fees. Starting on March 21st 2017, they stopped paying the transfer fee and the user now pays the fee.
Coinbase has blog post about it here:
