This guy used the same strategy of scammer bitcoin angel.
He gave you a bonus for you guys bring more people, the moment you began to spread in social networks his site, he did not already needed of you.
See, now he has a lot more people to fool or he had a lot more people to deceive.
The next time it appears that scammer, make sure you do not accept the bonus offered by it, not accept disclose his site and especially not invest money on his site.
I saw someone who says he lost many bitcoins, so the next time already know what to do!
