Is it legit will you get the bitcoin though if you win?
There is a Demo version & a live version. If you use the demo version (the one where you are not logged in), it is not real bitcoin and is meant for you to test the platform. If you log in, deposit your bitcoin and trade. Then whatever you profit, will right away be added to your balance and you can withdraw it right away if you want with no withdrawal fee.
Captcha nowadays is nothing more than an AI deciding humans can't pass as humans.

will see what I can do.
You can try it yourself, they have automatic payment system and they don't charge you for the transaction fee as well as withdrawal fee. You can deposit any amount to test the website. I tried already your website through the demo bet it was really entertaining and I won good amount but it's just a demo coin I will transfer coins when you officially open your website since I see that it was just a soft launch but I think it's good already.
Just wanted to point that although I called it a soft launch, it is ready to trade with real bitcoin. Its just that since it doesn't have the mobile version and few other features, I called it a soft launch.
