INTERESTING POST COLLEAGUE! I was also a member of that MMM( Mavrodi Mondial Movement). Even though it was a ponzi scheme, but the returns were awesome especially when you traded in bitcoin at that time.
Anyway, I first heard about bitcoin in 2013, at a seminar in my school. I was so scared to invest because everything I heard about it was perceived imaginable. But now, I have tasted and enjoyed the benefit of bitcoin and other cryptocurrencies. believe it or not, I am a strong advocate for cryptos.........
