how would you feel at it?
Beginner investors will feel regret because it has made them lose the opportunity to get bigger profits, but experienced investors are used to this so there will be no regrets because the price of Bitcoin will continue to move up and down and you can always take advantage of this, buying when it goes down and selling it when prices rise, and also if the 4-year cycle repeats itself then those who have sold it can wait for that period to repeat itself and before it happens continue to buy and study the market so that they will have the opportunity to get more profit than before
This means that indirectly in terms of investor response depends on how long he invests in bitcoin, because based on experience, the average person who is new to investing in bitcoin and gambling in the bitcoin cycle section will feel bored with the fairly stagnant bitcoin movement, but especially if those who buy in bitcoin at the top price, it will be more consider bitcoin as a ponzi scheme.
Meanwhile, people who have invested for a long time in bitcoin will be calmer and wait for their target to be reached, even though today the purchase price is much higher than the current movement. But if it's me, I feel calmer because I also invested in bitcoin for a long time.
