It means that those people who bought above $60k price bought because they were ready to invest in bitcoin as that was the right time for them. They also have the mindset to hodli for long and they didn't buy because they are after short term profit. This is the reason why they are still hodli their investment till now and some of them are even increasing their bitcoin portfolio because they understand the that the long term goal is superior.
Before Bitcoin went into this current DIP, many people bought at the pick $60k and above, it takes only a true Bitcoin investor who is well propounded with the knowledge of Bitcoin to keep holding till now. Many must have sold with disappointment and dissatisfaction of making profit only as investing into the market then.
I also see people that are new into bitcoin who have only little in their bitcoin portfolio, that feels because the price of bitcoin is pumping and for that reason they are over investing aggressively because they want to have enough bitcoin during the bull run as investors that plans to sell in a short-term which is why they are acting that way and if bitcoin price didn't turn out as they expected, they will be disappointed
Buying aggressively in advantage of the current DIP as to hold enough Bitcoin in my wallet before hitting a new All Time High does not necessarily mean am into short term investment. This is taking advantage of the market, having enough funds and accumulating very well is something that will benefit more not necessarily meaning will sell when the price climbs a little.
