Life has more things to do and enjoy than only trading and keep your eyes on the screen.
Moreover, the chart of Bitcoin
from coinmarketcap (see 7D time) with the fall and rally in last 7 days is very good example that hodling is better than trading.
Price falls and rallies, if you hodl, don't keep watching chart and screen every day, you would not panic selling. Then you will not lose your Bitcoin and price is still fine enough. 7 days ago and now, price is the same.
Trading with fearful is bad and only steal your capital and your Bitcoin.
