Those are short term investors not a long-term investors, a long-term investor will not sell his investment at any given time, and if he has to sell his investment due to health issues that is after using his reserve fund am sure he will be willing to start all over again because health they say is wealth.
But for those that don't have any health issues and sold their investment because of the price increase in the market are not good investors but traders, because no matter how he struggles to get the money to come back into Bitcoin investment, will still sell off their investment again when the price goes up again, these set of persons are known as perpetual traders that are always looking for opportunities to sell.
Perhaps you might have a misinterpretation of people's action, some guys who are selling or sold around $100k are not traders perhaps you might think all that because you're still a newbie here.
Some guys acquired bitcoin or bought bitcoin when it was around a thousand $1000 - $10,000 having made so much profit sold at $100k is not an act of trading, some of this guys even use the sustainable withdrawal practice to withdraw their bitcoins yet having so much left.
If you know what bitcoin really is you will discover that if it's not exchanged, transactions taking place then it's not longer a currency that Satoshi created it for rather it's just now an investment too.
There are many people who buy and sell their holdings when a small amount of leverage comes, are they investors or traders? They are definitely traders. Because investors will never express their desire to sell their holdings or sell them because of short-term greed. Investors will continuously buy BTC until they can accumulate enough BTC in their portfolio. And wait until their time limit ends.
If someone sells their holdings before the expiration of the term, even if they sell $100,000, I think they are not a real investor. It is not something that you will sell your holdings before the expiration of the term because you will make a lot of profit. If you have a certain amount of holdings, then you can take a profit by selling some BTC after 1 cycle or 2 cycles. This is completely my personal advice.
