I think you already know the answer. Never leave your capital in the hands of others.

Do you think I should continue with copy trading? I started with $120 and in 5 days I've reached $190, but previously I had reached up to $310 but a trader made a bad trade that cost me quite a bit of profit. At least it was profit that I lost; if it had been my initial capital, I would be crying haha. I've seen a lot of people saying that copy trading is very bad for growing capital. Do you recommend I keep trying it or withdraw and try something else?
