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.
The rates are higher now. With bitx, Hero Members can earn 0.36 BTC a month. But with 5 Hero Members at maximum capacity it will still be only 4 BTC in 2 months.
Ah maybe add 2 accounts again
you can join PM campaign too.
You can make 10 BTC in two months through BTC mining, but then you need firstly invest BTC in this 
How much i must invest? ROI?
it's impossible
