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.
Let us be sincere to ourselves even without having a Bitcoin investment emergency funds is essential in the general point of view provided that you are earning provisions for it should be made because unforseen circumstances will always be there just that many people pays less attention to it's importance, anyone that fails to plan is actually planning to fail, most of those good investments practices are also applicable in real life experience that should not be ignore and emergency funds is one among them.
Poor investors that sold their Bitcoin don't necessarily mean that they have bad financial management plan, it is mostly due to lack. With all your experience about financial management if you don't have funds to manage you can sell your Bitcoin to survive. I believe that investors that have the correct knowledge about the benefits of hodling for the long term will not intentionally sell their Bitcoin prematurely, it always has to be because they don't have any another choice.
Investments are secondary needs, your funds have to first cover for primary needs that are essentially for immediate survival. If your income cannot cater for your primary needs like food, there's no need to make provision for DCA funds because you will still sell prematurely to survive. Discretionary funds from where you get investment fund and emergency funds are important but the most important is funds for primary expenses. Poor people should try to think outside the box on how to increase their income so that they can have something remaining to put into their discretionary funds after their basic expenses are taken care of.
A person is to invest based on his capacity by DCA. A low income earner has a little discretionary income and could choose to invest the least possible buyable quantity of bitcoin which is slightly above $1 per DCA. The problem is that some don't have a life plan. You only plan with your stable source of income, not a random source of no specific amount. When you plan DCA, you make provision for every possible emergency situations first.
Selling off your bitcoin because you are poor is a clear indication of initial error in planning your DCA or investing today with no hope for tomorrow. Think life first before choosing a DCA amount. Anyone who thinks of long-term holding would never invest beyond his capacity because he could end up loosing part of his investments when the storms come and then run a loss.
It is ok to have a secured stable source of income but it is bad for us to have that kind of mindset of saying until I have a stable source of income I will not invest in Bitcoin when we have all it takes to start investing in Bitcoin at the same time working on improving our sources of income, all we need is a discretionary income to invest, even those on contract jobs not stable can invest whenever they have they received money and have a discretionary income.
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.
I understand that nothing is guaranteed but your stand on the future of Bitcoin is totally discouraging. If we don't have some level of faith in Bitcoin that it will give us good financial return in the future, how do you expect one to be committed to buying and holding? Some of us are not just following the crowd to buy but doing it dutifully as a retirement plan and part of what we will be handing over to heirs, with your position in Bitcoin, it brings some form of fear and skepticism. People who had this opinion a decade ago are today regretting why they never got started with Bitcoin the moment they knew about it; I'm sure 10 years from today some people including you will always regret why you did not take this seriously when others were taking the risk anyways. I will try my best not to allow this deter me because there is a saying that "no risk, no reward".
There is nothing discouraging at silvercryptobullet post he is right about Bitcoin investment not being guaranteed in the future, unless you are saying it is, he added that good management can reduce the risks and increases chances of success since risks can not be completely eliminated.
