Actually if you have 2-5 hero.member account, there's not too hard to get 10btc in 2 months.
How can it be done? I am sure it can't be done from signature payments as most campaigns pay only 0.1 btc per month for hero members.
With Bit-X you can earn 0.36/month with one hero, for 300 posts. I think it is the highest possible payout right now.
With 5 accounts and 0.0012/post max is 4.32/month.
Not too far from 10 BTC/2 months, but you would need make 1500 posts/month
