Even if we do everything perfect, we are still not guaranteed to make profits - even though if we engage in strong cashflow management practices, then it becomes less likely that we are going to be easily shaken out of our investments based on sloppy practices.
No guarantee about future and existence of Bitcoin so no certain profit from our Bitcoin investment. There is always uncertainty in everything we do, including our investment, with probability of profit and loss. Good management is helpful for reducing risk while increasing chance of success but there is no management that can completely eliminate risk.
There are a lot of newbies and/or even poor folks who do not engage in good cashflow management practices, and they are more easily shaken from their investment as compared with a rich person
In other words, poor investors likely need to make more preparations to make sure that they are not shaken from their investment, yet even if they do everything perfectly, they are still not guaranteed to be profitable in their investment, yet if they do not make the proper kinds of preparations to make sure that they have strong cashflow management systems and practices, then they are increasing the likelihood that at some point they will get shaken from their investment..
The poor investors might not want to shake out their bitcoin too soon but by having bad financial management, it leads to many bad things consequently including their cashflow management and unexpected sales. When they suddenly have needs of cash while they don't have cash for emergency, they have to sell their bitcoins unexpectedly. If they can hold it longer, they might have profit and I believe they know it too but it's just they have no other choices and are not able to hold in urgent situations.
