I replied to the mail (no answer yet):

Dear Admin of MakeBTC.org (that is: if you are the real admin of that site...),

Personally, 'till a few days ago  I didn't think your scheme and website "got a wrong way", as you put it.

But why do you need my email- and password? You send me this email, which proves you already have my email. Besides, I registered a btc-address in the MakeBTC-database to send me my income. You can use that address to refund and pay me the bonus you just promised. Regarding to the sudden disappearing of MakeBTC, I think it's more justified that I ask you to prove to me that you're really the admin of MakeBTC.org before I give you any password or other info.

But surely, I would like to get my deposits to MakeBTC.org refunded. Therefore I would highly appreciate it if you send me my full refund incl. the promised bonus within a couple of days from now. You can send it to my btc-address registered in the makebtc-database, ore simply return it to the btc-address of which I send my deposits.

With regards,

Kush
