As personally, I believe we have to follow the footsteps of top traders as well as we have to build our own strategies to trade, who knows your plans can give better results. But as a newbie its better if we follow the top trader and learn from them as they can teach you things you cannot able to explore yourself in short time and you can add up your own brain and efforts to make a reliable trading plan.
Happy Trading
Following them isn't wrong in the first place especially for newbies. You can take their shared strategies as reference for making a strategy.
The real action is doing the actual trades. This is the time you will test if the strategy you got by either following others or created by you will be effective in the long run. Honestly, you can't copy literally the other's whole strategy even you want it as it relies on different factors so for this you need to rely on your own.
Don't regret if you will lose on the way, that's common. Even professional traders today losses. Take mistakes as a lesson.
Experience will teach you how to be a better trader.
