It is a newbie platform, nobody gives the try to copy/paste their strategy coz we know what it possible ends.
And in the first place, there is no reason why we have to follow these people for the fact that they never give any proof that their strategy really working. Following them, do the copy/paste isn't learning of becoming good in trading but this gives us a reason why we fail.
Besides, we can learn trading without these people, we can make our own strategy from the ideas we get watching online trading and from our friends.
Binance has something like that.. sort of? There is a place where it allows people to share their profile, I do not remember where it was but I remember seeing a guy who turned 70k into 1 million dollars in the past 1 year using leverages or something, he bought futures a lot and at the right times when bitcoin was moving up (which it did mostly this year) and he made that kind of profit, and I have seen his profile and how he made that money, which is why I know that binance has it, just couldn't find it for anyone else (or even find that person again), hence maybe I am wrong.
It is really not a smart move to follow someone because even if they made money once, doesn't mean that they will keep making money, that is the biggest challenge, making money is possible but keep doing that for a very long period of time may not be something successful, hence that is why I stay away from that.
