Holding is better than trading. If you buy Bitcoin, and hold it from 2017 to 2020 or 2020, you get profit.
If you buy Bitcoin in 2017 and trade it in 3 to 4 years to 2020 or 2021, I am not sure you will have profit now. If you use margin trading, I believe your orders would be liquidated many times in 3 or 4 years.
It's easy to say that since you already see what happened. You can't just say to others, hold for years.
I even doubt you will do it. You won't know what will happen within 3 years.
Holding and trading, both are good. The result will be based on how good you are doing it.
indeed the most difficult is to keep our emotions to stay focused on the goal. to hold in a floating plus condition is not easy, especially if we look at the market too often, of course this will make us undecided between staying hol or selling, because we don't want the profits that are already in front of our eyes to disappear again
