This page says it but you almost can’t say it enough, go in with your eyes WIDE open.
You can lose money even when you pick a so-called ‘Winner’. They’re not Warren Buffet so don’t expect they’re going to make you a millionaire overnight.
It’s like any investment really, do your homework, start small, and get out while you’re on top.
That’s my advice anyway from years trying to crack the trading industry and copy trading more so in recent times!
