Freebitco.in FROZE the provably fair system in WOF bonus

This is the video that I made:

I show that I played much more than necessary to unlock the captcha.

There is nothing that can be understood from the Youtube video you had posted apart from showing the requirements and clicking on a free roll with captcha. Did you try clicking on 'PLAY WITHOUT CAPTCHA' to try the free roll without captcha? The minimum payout keeps changing based on the price of BTC. You can also see in the same free roll page, the % you need to increase the bonus. This is based on my understanding.
