Well that's really one of the way that can earn 1 btc for a year, for me 1 year is really a long time to be able to earn 1 btc. But that's fine if you are going to work for it really hard and after you hard work you can spend your earning in a right manner. You can sell also some digital goods, accounts that can be use by other member if you don't want to use it anymore, like twitter with thousands of real followers.
