Copy trading is the worst way you could choose. First, it's crazy to repeat someone mistakes and loose your own money because of someone's stupidity. Second, don't think that trading is so easy that you can just copy someone's strategy and it will work. Excuse me for these words, but life is pretty fair and you have to be responsible for your trades, your wins and losses. Only your own experience, understanding and vision of the market will help get profit.
Without doubt, copy trading will never help you get fixed profits. Actually, copy traders have always been sort of frauds.
