That's why HODL is very important but holding Bitcoin as of now is not the best choice the best way to go about it is by trading. But it's very important to HODL when the price of it has not yet increase more in value or if It falls back again.
Many of them regret it when they see the Bitcoin price movement which can rise to this expensive price. Have you ever known of a case where someone bought 2 pizza pans and paid for them with 10,000 Bitcoin? Imagine if he was still holding bitcoin, perhaps he would now be one of the richest people in the world, but that's bitcoin, no one knows what the price will be, what is clear is that holding is the winner.
Think about the 10,000 bitcoins. If I multiply it by 70k, the equivalent value is about 700 million dollars. That's a huge amount, and you yourself will probably have a problem with how to spend it. But even so, something happened that should not have been done before, and probably the person who did it is very sorry that he made Bitcoin pay for just one pizza.
So the holdings really provide a lot of help if we are patient, stick to the plan, and don't give in to impatience or panic. Just stay positive, as always.
