There is an easy method of using faucets etc but you will earn equivalent to the work you have put in. Not much. As with real money /fiat/ there is no easy sure fire way to collect btc easily. You will need to work for it either offering a service or your skills and that is the only method you will need to collect btc.
After seeing the prices of accounts recently I would say that it isn't as easy as you may think. How long to rank an account to be able to sell for 0.05btc. To long and not easy to post that much without getting banned for spamming..
there was an user posting with 50 account and he was not banning, so just do not post no sense and remain on topic, i see no reason for anyone fearing the ban if he is genuine
reaching a member or full member it's not so hard, we are talking about 4 months, but bears in mind that you can create many account that can reach in 4 month that rank
so you can easily earn 1 btc every 4 months, plus the earning from signature
