Well, bro, Good thread. In my opinion, I think that It depends on one's grasping power and commitment may be even after spending month on demo account one is not expert enough to trade on real account and may be just few days practice may make one good trader.you use the demo account as long as you get the maximum training and practice and you feel that now you are ready to make a trade in live account then you come in real trading other wise you getting the loss in real trading. .Good pips, bro.
