Honestly, I would keep away from every single copy trading scheme out there. No matter if it's for
Eur Usd or for
BTC USD or whatever. Why would I advise everyone to stay away? Because you never know who you are copying. Is it only one person? is it a group of traders? do they have a risk and money management? Are they all healthy, or are they sick when trading? Sober or drunk? can you really understand their process behind their trades?
And most important: Why do others want you, to join their copy trading thing? -> they earn commissions for every trade placed and referred to them.
They don't want you to become financially free. The best result for them is when they have 10 trades around break-even, and then one with a small gain. This way, you would not stop copying them, but more than likely leave your account like it is. Maybe even tell your friends about it. As long as you don't start to lose, and sometimes even win some, they can earn from the commissions.
So their only goal is: Get as many people to join their "Get rich quick and easy" scheme, so they can earn those commissions.
If you want to learn how to trade as someone else does, that is a whole different story and I would encourage you to do so, after observing this person for quite a bit!
