Damn, that was one big winnings. Although its much better if your friend can really shows us the screenshot of that jackpot so that we will not doubt that this is just a 7bitcoin.com marketing strategy.

How much though is the capital of your friend? I'm just curious because if he spend less, that even 1 BTC, that's already x10, however, its not a big win if your friend spend close to 11 BTC. Anyways, just spend your money well.
