Yep.. this is another aspect of selling too much too soon, and not realizing the value of the asset in which they are investing (in this case BTC's value).
There are a variety of ways to engage in tactics that help from selling too much too soon, but a lot of it is easier said than done.. because it becomes so tempting to sell a very volatile asset (such as BTC) even when it might ONLY have 50% profits, because there is nervousness, and frequently there can also be a lot of hesitancy to buy back and waiting for prices to dip, when they may not end up dipping.
So strategies to continue to buy should attempt to both account for up and down volatility and also account for better odds to NOT get so wrapped up in short-term BTC price volatility, continue to buy and consider the investment to be a 4-10 years or longer investment, and sometimes even more than 10-year timeline is necessary to improve psychology.. and of course, there are also no guarantees that BTC prices will continue to rise, but seems that BTC upside asymmetric nature continues to be good so that if people are investing modest amounts, then there are likely decent chances that they will be in profits 4-10 years or longer down the road, and perhaps even in better profits than any other investments that they could have made... and then sometimes, at the same time, there can be questions about how modest or aggressive a BTC investor should be? My own personal philosophy has been to attempt to be relatively aggressive, even though I understand that sometimes people will overdo it, even when they believe that they are being "relatively aggressive" they have not sufficiently prepared for emergency funds and various cashflow crunches that they may suffer from time to time along their journies in life.
The most important characteristics a bitcoin investor should strive to develop is the ability to resist the temptation of selling off too soon and also getting too greedy at some point, blinds their sense of judgments, in managing a proper cash flow there is need for the investor to develop an accurate financial management approach that always provides an extra liquidity that could sustain them through the long term journey since most of the crisis arising from Bitcoin long term investment is as result of the investor's inability to take his financial burden off their Bitcoin assets and also over-reliance on the anticipated profits on their Bitcoin investments and their inability to build the right financial knowledge that could sustain and guide their financial actions since we are in a volatile market like Bitcoin whose future outcome is always unpredictable so there is a need to an in depth understanding of the financial market as an investor in other to know when to ride on a dip or take a look at other asset that could possibly perform on the same line with Bitcoin or competitively.
I am not a financial expert yet but i have build some financial values that help me navigate through, as a newbie in financial analysis and this have helped me greatly to make the right financial decisions when it comes to Bitcoin selling vs buying - holding vs selling off to cash in on profits and in all this, i understand the place for (RIGHT TIME) because, acting at the right time is what differentiates a nobs from a pro in financial actions.
