Yes it's possible!! Some signature campaigns pay about 0.09/month around with the avatar bonus which is more than 1 BTC a year. I'm talking about betcoin campaign.
Am also looking forward on how I will be able to earn 1BTC in a year. But somehow suggestions here are very nice that we can actually do this as possible.
one year for a whole year isn't a very low income? it would be great if we can earn 1btc in one month.. I think it is possible with hard work and dedication. only signature campaign won't help it.
ya should not depend on signature campaign, signature campaign did not spend a long time, so you can use the many ways in one time.
