maybe if there are method is copy trade which nowadays there are some websites that allow people to do copy trading so we can copy what other people order right after they execute it, but there are no guarantee if we will always get profit in there.
Copy trading is very much similar to buying signals and as far as I have watched none of my friends were profitable through copy trading functionalities as they need to pay monthly subscriptions along with losing trades.
I have seen many traders who are buying signals, trading with the help of bots for automated trading and copy trading by following pro traders. But at the end of the day, there are a lot of other criteria we need to consider for making consistent profits from trading. Because, just getting signal alone will not decide our profit/losses in trading but timely decisions and how many positions we are taking and how we are making use of trailing stoploss kind of things are more important even you are getting very good signals from any of above resources.
There is a tiny difference of the trader actually trading what they suggest you as well. Signal groups gives you something but they are not required to do that themselves, they may or they may not but that is not a requirement. In copy trading, you see what someone does and trade accordingly, so if you lose money that means they lose money as well and that is not something anyone would want to do which is why you have an added pressure of both making others money but also making yourself money there as well.
Buying signals is just building a bot that notifies when BB drops under 20 or something like that, indicator and numbers could change but the idea is very simple and it is understandable when they lose money as well, because it is too simple of a calculation for bitcoin price prediction and if you underestimate bitcoin then you will lose a lot.
