till now i try to withdraw my earning but it is always pending!!

Well good luck OP because more often than not it would be pending forever. For HYIP sites, if you heard someone that its not paying anymore then you should immediately withdraw your funds if you can still withdraw it because its a sign that the site would go offline anytime. The better way would be to avoid investing in HYIP sites because most if not all of them is scam.
Lesson learned. I guess the guy is just new in investing. ButI have a feeling this guy will still invest on HYIP even though he already got scammed.
