Because that still says "NEW!!!
ONCE THIS SITE GETS 1000 BITS WAGERED, WE WILL HAVE A MASSIVE GIVEAWAY! OVER $100 IN BITCOINS!!!
Also, I will give away .5% of everything lost, so if you loose a lot, you can have some back!!!"
So, someone has already wagered 1000 bits. How are you planning on giving away massively?
It doesn't sound right at all. Why would he give away $100 (~440000 bits) after someone has wagered just 1000 bits? And why would he use a free hosting if he has planned to give away $100?
