So, is copy trading legitimate? Yes, it can be a legitimate way to invest if you do your research and select the right traders. However, it's important to remember that there is always the risk of losing money, even with copy trading.
It's trading but it's kinda not worth it, the risk is not worth it because if the master traders win some trades, your profits are kinda low because the master trader got their share and if you lose, you lose your money.
For me, finding a good master is good especially the master trader got good risk:reward ratio even over the time profits is low, as long as it is stable.
