They scammed me with 300$. They came to me through LinkedIn a guy named Frank Williams and he told me to buy bitcoin worth of 100$ which took me 200$ to make it 100$ due to transaction fees. When I blocked him on WhatsApp then Another female approached me last night and she said that I have earned 5200$ from those 100$ and then she told me, to withdraw those 5200$ I need to purchase another bitcoin worth 100$ in order to withdraw the funds and then when I paid another 100$ they received 67$.
