You are right that some investors do not have an idea about emergency funds and how it works but rather, they solely depend on their profit, which sometimes does not go down well with them and when their business begins to shake or have issues, they sell their assets just to solve the problem and in some cases when it overwhelms them, they get frustrated and that is the end of their business.
I once had no idea about this aspect of emergency savings till it dawned on me. That was when I realized that I had no savings. I made a budget for it and began my emergency savings, and it has helped a lot when I am in need of financial backup.
Sometimes investors do not realize the extent to which they are lacking in back up funds until they think through the situation or an actual emergency comes and they have no fall back... So, it remains important to have some thoughts about your set up before you end up in some situation that you had not realized that you had made yourself vulnerable. These matters become more important with an investment like bitcoin that fluctuates a lot, and if any of us make investment plans that go out 4-10 years or more, then we likely have to try to figure out ways that we are not tapping into our investments at all, but especially at times that are not completely of our own choosing or at times that we are not able replace any bitcoin that we might have spent.
Sometimes newbie investors will also play fast and loose with their bitcoin investment, and even if they might have a plan to invest into bitcoin for 10 years or more, they will find that their bitcoin holdings are extensively in profits at a time that it still early in their investment, and then they may well end up fucking up their investment because they try to trade it.. and then they may well end up selling too much too early or ending up with way less bitcoin than they would have had if they had stayed focused on ongoing buying the bitcoin until they get enough bitcoin or more than enough bitcoin.
Surely anyone on the internet cannot resolve your situation, so it remains important that you figure out some systems that will work for you to reach your goals, and if you are trying to accumulate and build up your bitcoin, then it is good for you to think through the various aspects of
your personal factors to make sure that you have put good systems in place that are tailored to your own financial and psychological circumstances.
I agree with your postulation that many investors make the mistake of not having backup funds, and this they fail to understand. Ordinarily, for every investment one ventures into, there must or should always be a backup fund to avoid falling back on their investment. I have realized that many investors have this mentality of the fact that since the business or investment is theirs, they could dip their hand into their profit and make some sales or take the profit, which goes against the main purpose for which that business or investment was set up and when they constantly engage in such practices, they derail the main aim or profit target for which they had initially setup the business for. Ever since I learnt my lessons, I always try my best to not think about my long-term Bitcoin investment after I did it and before I did it, I had a plan of saving 15 percent of my salary every month and from other proceeds as well so that I do not put eyes on my bitcoin investment for the number of years I planned holding it.
This act of falling back to business profit has caused many businesses to fold both Bitcoin investments as well. You see, they would look at their Bitcoin profit and be like Oh, I am in profit, let me take this profit and sort things out immediately and so doing they continue to tamper with their investment till it dawns on them that they have altered their bitcoin investments plan and target because they have no savings to backup their emergent situations. It ends up in a bad state, where they lose everything at the same time and have nothing to hold onto. Many businesses today have crashed because of this carelessness on the part of the owners and holders of Bitcoin assets.
