Just join any signature campaign, you can earn a lot. My target is to get 0.4 BTC this week from mine signature. Hope I will find time for posting.
I have 0.2 BTC now. I think I can do it. If you want to stalk my earnings check

Wish me luck

How many posts for you need to reach 0.4 bitcoin? Sounds like tons of work
I got this for 2 days of posting in my pool (

) so no work for me. My rate is 0.0013.. it's about 320 posts ( Just got this from my head, better use a calculator if you want it correctly ). I try to post constructive and quality posts so I can get higher rate, but it's really hard for me because I'm lazy.
