Copy trading? Heck I won't even attempt that kind of strategy, even if it counts as a strategy.
I also do software development and it's like copying someone else's code with just changing variable.
I don't think you'll be able to analyze and study the market itself by doing that, well sometimes you can't really understand the market because coins have their own volatility in price anyway.
You have a point, But newbies on programming do copy codes or rely on pre-made codes on the internet for them to imitate it or figure out how can they do it. In the process of learning, It is very helpful to rely on something that has been proven and just figure out how they did the original owner do that. Copy trading isn't that bad if you are learning from it but if you just rely on it forever without learning anything well that's just like copying someone else code and just changing its variable for your own good.
I believed that we have different ways of learning and finding the most efficient learning for yourself is the best. As long as we ended up on our goal, It's fine.
