I've lost over one thousand dollars in synthetic indices and I've never withdraw money to spend, my relationship with that instrument is sort of a love hate thing, I will still go back to trading them probably this year, indices are basically the first asset class I've traded live and they were good to me, I quickly flipped my 50 dollars to almost 112$ but shot happened when I took someone else's money to trade.
Initially it was successful but I later gave everything back and went out of business , I never got to trade them again till today
