5% fee is too high for this ponzi.
OP already earned 40BTC+

Hmm.. got to agree now. I suggest him adding advertisements and get his 'salary' from advertisements (and maybe.. one or two percent) .
even 1% will give him much money.. 700BTC*1%=7BTC($2,000) in 1 week
Hmm.. might be true, however, he/she/they need money in order to run the site. Well, if I'm not wrong, it is running on a VPS. A VPS is really expensive!
What's more? They might need to have (stronger) DDOS protection in the future if they are bigger..
