I recharged $200 to my account, I traded and made a profit of $70. I later increase my capital by $100 and I was having a total balance of $400 when I decided to withdraw, I was asked to pay a withdrawal fee of $50 which I did, I withdrew my $400, but I was only paid $4 in Bitcoin to my wallet. I message you customer care but to no avail......Have I been scammed?
