what is the minimum amount of deposit to have direct roll without captcha
This question has been answered multiple times in this forum thread, but here's the answer once again:
To remove the captcha you should deposit a Bitcoin amount equal to the amount of your free roll earnings. You can see your current free roll earnings by clicking "Stats" and then "Personal Stats". For example if you earned 0.001 BTC from free rolls, you should deposit 0.001 BTC to your FreeBitco.in BTC deposit address and the captcha will be removed.
A simpler way of putting it is that you need a balance of double your total free roll earnings. You don't have to deposit it, you can win it from gambling or earn it from referrals as well. But the point is, there is no minimum amount.
this my account but i'm still solving captcha. is there any idea about that?
