Of course, my mate, I also agree that you should take this route for a side job in which you don't have too many problems. It means that you should make this work your hobby, which is in the field of your liking, and the second is that there should not be too much physical labor in it. Only interference should be done in this job that you find equal to your physical strength and happiness. Anyway, side jobs only mean extra work, so why should you take so much effort for it, which will leave your essential work or cause pain for you? Yes, side jobs mean to increase your financial status, but that does not mean that you should choose the jobs that leave you from your essential work or jobs. Which is your main source of income?

I totally agree with your opinion about choosing cryptocurrency as a part-time job because it does not require much physical effort; you can easily do it at home, outside, gathering, etc. without any physical effort. I would like to say one more thing about cryptocurrency: without knowledge and experience in cryptocurrency, it can lead to loss instead of profit. Because the foundation of cryptocurrency is based on volatility, So, you should monitor cryptocurrencies carefully and thoughtfully.
