Why play with 50% house edge ? I have understand bad ?
I can not help you.
Better ask the people who play.
Maybe because they can win with 0.01BTC 200 times more!!!
Thank you.
In fact i think you are the right person to ask. Its almost certain that there are no "people who play". Only you playing on your website, maybe automated, though the website doesnt look like you would care about spending time on coding such thing. You wouldnt lose anything since all coins come back to you.
This is your opinion. I have regular participants. Some of them are my friends. I have spending a lot of time of design and build this site. Take care!!!
