What is amazing is that (at the time of this writing), they've had 205 BTC deposited. At today's value, that's $140,000 USD. For a site that looks to be just over one week old.
In a way, this is almost sort of like gambling. You either get 1.2x your money, or lose it all. Odds depend on the hype of the site.
