I just came up with an idea to "cheat" the referral system of freebitco.in
Here's how it works,
Sign up with my referral link --->
http://freebitco.in/?r=349187
---> put captcha every hour ---> I will share the earnings based on total referral activity ---> Profit
Here are my calculations:
Current minimum win: 0.00000433 (This may change depending on the site)
For every captcha you get, You will have 0.00000433BTC. And with the referral system, I will share the 50% of the referral earnings to you which is 0.00000216. Then with that, you can have 0.00000646 BTC. Which is pretty good vs the normal amount.
I will share the earnings once a day.
The more you roll the more you get.
