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.
You are right, holding bitcoin is better than trading in the long run because traders will end up incuring losses. Trading is very broad and complex which makes it difficult for you to learn easily and start making profits. However, hodling bitcoin is easy with less stress as long as you are using your extra funds to buy bitcoin and have long-term mindset, you can hodli and reap your profits in the future.
Bitcoin investment is undoubtedly much easier, risk-free and more profitable than trading. Trading is a very difficult subject, as much as a trader initially thinks trading is easy, the reality is completely different. Although trading seems easy to see and think about, when it comes to you do it in reality, you will not be able to trade easily, because trading is not an easy subject. Bitcoin investment is much better than trading, if you hold it consistently with faith in the long term, Bitcoin investment can bring a huge amount of profit. Holding is the easiest, safest, most profitable and most popular method.
