I was approached by a man on instagram promising that they could double my investment within 7 days using their special Technics and analysis. 90% success rate. he referred me to 2 websites, 7bitcoiners.com and poweroptioners.com Where i had fund my account. but what was funny to me was that i had to send the money through his bitcoin wallet.. I did ask him why this method, he assured me that i need not worry it will show in my profile. long story short, the problem started when i wanted to withdraw my funds/ winnings the so-called admininstrator of the site wanted me to pay the equivalent of the winnings to a bitcoin address for me to get my winnings. Now i am demanded to pay them $1000 before they can release my earnings.
