I was invited to Whatsapp group. I invested in mhtcoin.net. When I wanted to withdraw my money , then I stuck in problem. mhtcoin.net representative asked me to pay taxes in order to withdraw my money. I told them That they can take from my account these taxes and let me withdraw rest of the money, but they want my payment.The professor "Michael Novogratz" and his assistant Alice are fake.They have fake conversations on the group to appear knowledgeable.i filed a complaint with (Apexaid.org) experts online, after completing the form on their website. They tracked and traced all the payments i made. i got my payments returned after few days i got in contact with them.
