Every method has risks. But if you can accept the risk and have learned to reduce the level of risk that we can accept, I think it will be a valuable lesson for us to introspect what we have done. I don't recommend using copy-trading because it's not easy to find real pro traders, and usually, those pro traders use big funds to trade. That means we also have to prepare large funds so our profit level can be greater, and not everyone can have much money to start trading. Another way is to buy bitcoins and keep them for the next few years doing nothing.
Those copy-trading people who are willing to share their trades are usually people who would like to promote themselves and that's not always bad, but usually that's a bad thing. It means that they do not truly care about being right or wrong, they care about being followed by as many people as possible and that usually entails getting right back to back, so the "goal" is same, if they make you money then they get famous, good for all.
However, they won't care if you do not make money, they won't be famous and that's bad but they do not lose anything, they just fail to reach their goal, on the other hand you would be losing money and that's not fine.
