Today I see the market starting to recover and bitcoin is trading back above $105K. Anyone who accumulated on the dip the day before has seen how well that approach has worked so far - that's how the market rewards those who use it correctly. Don't be afraid when the market goes down for one reason or another - it will eventually recover for a reason.
Some people are hesitant to buy on dip - even with some of their capital, but the reality is that they are too often late to act, especially after the market recovers. It is okay to buy on a rise - accumulation can be done at any price, but when you take advantage of dip, you will obviously accumulate more bitcoin.
You are right, that's the truth about Bitcoin. Many people are afraid when Bitcoin falls, but those who are smart take advantage to buy more. As you said, those who bought during the dip are smiling now because the price has increased again. Some people wait too long, and when the market rises, they regret it. I believe it is a better choice to buy more during the dip since the market is going to recover. Even if you don't have a lot of money, investing just a small amount of it when the price is low will help you accumulate more Bitcoin.
However, the Bitcoin market is not about fear, if you understand the game, you will realize that the dip is not a sign that Bitcoin is over. It always comes back. So it's all about taking your time and knowing exactly what you're doing instead of rushing and panicking.
