Trading is not for free time and not for life time either. Trading is for that time when you can analyze a coin and understand that it can hit your prediction perfectly. If you do not have good knowledge about trading or market analysis, then you should not trade at all. Because at that time you will not be able to achieve anything good from trading. If you use trading only for free time then it will be equal to gambling. Because at that time you will never be able to take entry in potential coins by better analysis. And then you will lose in trading if your luck is not good at that time.
Trading is a full fledged job that perhaps requires even more than a regular job you can do with average knowledge. In trading that will not work, you need to have deep knowledge and more importantly a lot of experience. But even then no one will guarantee how much you will earn. I would also like to draw your attention to the fact that holding Bitcoin almost always outperforms trading, keep that in mind. And if you do not believe it, test it yourself, maybe in your case it will be different.
