I thought no body talking about this,, finally ..
well, i had received free BTC and made a few times withdrawn from this site without made any Deposit, absolutely with no problem .it's about few month never check this site. just made another withdraw few hours ago,but in waiting process..usually it took any second to completed the withdrawn. now seem they change their rules about payment it took about 7 days business day. so, in my opinion in this situation better don't risk your money if you are not really sure. or, take the small risk if you wanna test it. (I didn't recomended this,but it's up to you).
