So my question is really, Are they ever actually worth it? has anyone ever made much profit from these "premium" signals other than the people that run them? or could it be how I have the Cornix bot set up?
You shouldn't have joined the trading signal group in the first place because they usually use to scam people in the end which is the reason why you are asked to subscribe again and my advice is to learn crypto trading, there are some Youtube video that can help you with that.
I have followed some guides but I wonder whether I should try and commit the time to learn to trade manually without the use of Bots? It's just a nice idea to have passive income while I am at work and asleep.
Bot trading ease the burden of spending much time on trading.
You can commit your time to learn trading and also use bot rather than signal but none of them guarantee every trading decision you make to be successful.
