You take 5% for picking a number at random.org ?
Every dice game has a lower house edge...
And how do you verify that the number was the first that you generated?
I will have to send 3 transactions which will cost me 0.0006 BTC which means my profit will be 0.15$. Which is not too much for making a video uploading it and then moderating this post
To your second question every time i can make a video and upload it here. I will not take any bribe to change numbers lol no. Thats where i will earn the trust.
