Just imagine, “you simply let someone else develop the trading strategy for you by directly copying the exact same trades they make”. In addition, you can analyze and study the crypto market and strategies you followed, and interact with the traders.
That's a wrong mindset to have, blindly copying some random users that claims to be a professional online and shows you all sorts of proof that can be edited without you having any clue what's going on. Trading isn't that hard to learn the basic and with that knowledge you can start your enjoy in the industry while you let your experience and other additional knowledge you'll acquire as the journey goes on, to help you become a profitable trader.
You stand a chance of losing more if the trade (signals) you copy goes south, the fact is they (signals providers) can't be accurate all the time and in chances when they're wrong you don't have the privilege to learn form the mistakes that resulted in the trade going south. I won't say much since I believe other responders must have done justice to this topic already.
