You don't have to respond to anything, you do what you think is best for you, it's your time and your money but after being down as many are to the tune of 90% on Sfor investment I would not touch anything to do with Mark and Sfor.
I do not blame anyone, it was my decision, my money, I made money and lost money on stocks
I will stay with Sfor until the end not because of my trust in Mark but after 3+ years I feel maybe pps will rise and I figure if I lose my remaining money, not a big deal anymore.
Take care and I wish you much success
