We have seen this scenario so many times before, relax and try to accumulate more then HODL, I believe most of the old crypto earners are doing this.
I agree with your opinion, and indeed if a beginner will definitely be discouraged when they see the price of BTC going down, sometimes beginners usually always panic sell even though they are at a loss. And to be honest, when I first got to know Bitcoin, I personally also had the experience of always panicking when after buying BTC the price fell. However, those who have experience will definitely not be discouraged and panic when they see the price of BTC plummeting after a high price increase.
Yes, of course, in this case, those who are experienced are familiar with seeing the bitcoin cycle and those who are experienced always accumulate bitcoin when there is a price drop and use money that is ready to be will be lost and of course keep it for the long term and only sell it if make a profit.
However, according to my research, beginners usually don't learn the knowledge first before jumping into Bitcoin, which in the end has the potential to experience losses, including panic because they usually don't use the money they are ready to lose to invest in BTC.
