Obviously you are correct, but then, before that time will clock, many of us might have sold our bitcoin for frivolities. Do you know how it works;
I will just sell today and hoping that I have fiat to buy again tomorrow, but procrastination will play in, and I will forget about buying and eventually the price will abnormally rise and I will miss out the opportunity. If you look back the wallets you have used in the past, you will regret how you spent your BTC in the past.
It's true that you say that many of us sell Bitcoin because of trivial things, but that could be because they really need money to meet their needs. That's why they sold their Bitcoin and it was a difficult choice for them.
Why do people go into Bitcoin investment with setting up an emergency fund or a form of reserve to take care of expenses and emergencies when they arise, because surely emergencies will arise in the long run and without the availability of an emergency fund, one's Bitcoin holdings would be the only option available, and when one always run to their holdings to sort out other expenses, the value and strength of your holding would drastically become weaker and this isn't good for investment.
People should always prioritize setting up emergency funds to avoid scenarios such as this.
