There are a lot of factors that determine the success of any trader. Copy trading, while it helps newbies to copy the strategies of successful traders for themselves, does not help the newbie in the long term. You have to develop yourself, start from the basis, read books, watch videos, and start small. Don't be greedy or emotional in the market.
Even copy traders make loses sometimes. So if the trade goes wrong, then you also stand the risk of losing your funds.
Copy trading can help in the beginning but depending only on that blindly and risking your money there is surely not a wise choise. If you are a beginner try copy trading with some small amounts and learn from that, and then use your own brain to do trading.
