Holding is a very stressing strategy. You may be rich or poor in one day. Trading is good as you can lower the risks but if you're not free then you can't now do anything at the right time
Its the other way around, trading (day trading) is stressful than holding. Imagine a day trader have to go through when he bought a coin and within a day he needs to sell it with profits based on his personal goals, and that can't be done without monitoring the price of the coin so you can decide and sell right away. Compared to holding (long term or even short term), lets not look further, just check how much BTC is 2 years ago and compare to the price today.
Both trading and holding of the crypto coins have their own advantages and disadvantages and that it is you who must make the choice after keeping all the things in your mind but you must be sure that you are making the right choice and that if you are willing to go for trading, then you must have enough of the skillset which can then help you in making some better strategy for effective earning.
