oh,you surely do
this is an obvious ponzi scam,if you were lucky to return your money,doesn't mean the site is legit
they end up the same ALWAYS-the first ones get profit,the ones who join later get shafted
then there is this "hacker attack" or "a FBI takedown" or DDOS or whatever the reason they find to make an exit
promoting such a thing is encouraging scammers to build more of the same scam sites
