1btc a year.. you can earn that in 1yr by faucet. everyday... but you can earn 1btc in just one month or 2 months by doing another way.
try coinbase register there and invite people to join to your referal and if the referal peorse got buy 1btc on coinbase you can earn 0.1 plus btc. invite more and told him to buy bitcoin and you can earn btc much easy and afast...
You find easy to find other people to join coinbase and for more even to buy bitcoins in the amount needed? This way is almost impossible to be used for the simple people. So is useless.
but coinbase exchange run only for some country (based US and UK) not avaible at asia
