Hello everyone 

I'm new member. I gave an important question; sites who want you pay to activating whithraw like btcgreat.com are safe? I mean they didn't say anything about plus amount for activating whithraw before you make deposit.

for example I make deposit in btcgreat.com 30$ in first plan: 600%  then I checked my account balance and I had 180$ but it's pending! They sent email to me : you should 150$ ones for activating whithrawal instant system. Is there Anyone with experience same me??? You paid ?? And site paid to you???

thanks plz help me

An investment program that offers 600% after just one day is purely a money game and not a real investment opportunity. So you should treat it just as it is a gambling opportunity. 

If they ask you to deposit more money i think they simply want to scam you so they will get more money from you. I wouldn't pay if I were you and I will definitely avoid spending money in sites with such unrealistic returns.

There are some monitors that list this program as Paying http://www.allhyipmonitors.com/details/btcgreat.com?final=1 So contact the administrator and tell him that if they don't pay what they owe to you will report to these monitors.

Keep us informed.

Yes, that's true! I know more scams on forex market. For example, Exness increased margin requirements without informing their clients and many people lost their money.

Any news on this matter, @Yasi ?
