We almost always make a mistake (not everyone, many) and that is, when we make a long-term plan, we do not create a support fund at the same time. How does this happen? Let me explain a little more, a long-term plan is a plan that is implemented over a long period of time. And a long-term plan gives us a little more profit. If there is no support fund, that is, if that fund is not used during a disaster during this long period, then it is natural that the planned long-term plan will be damaged, so before making any long-term plan, we should always create such a support fund, whether it is a stable income or a volatile income in my opinion.
You have been registered on this forum for a long time, and I believe you have been posting in this thread for a long time also, but I am surprised to see you say that we don't make provision for an emergency fund when we are investing in bitcoin for the long term when an emergency fund has been discussed in this thread so many times. All old investors in this thread know about the emergency fund and the major role it plays in bitcoin investment, so I believe all old investors who have been investing in bitcoin for the long term have made provision for an emergency fund so that they could probably solve their unexpected problem anytime it arises. Since most businesses in a country accept fiat as a medium of exchange, it is better to save your emergency fund in fiat so that you can easily use it to solve your unexpected problem when it arises.
I think you are getting what @MissNonFall9 is saying all wrong because all i can see that they are talking about is having a support funds otherwise called backup funds which can also stand as emergency funds. However, the need for keeping emergency funds is for immediate needs that may happen in the future such that instead of you to cut out your investment along the way to attend to such emergency you can just cover it up using your emergency funds you have kept while you continue with your hodling. Normally, emergency funds must be in Fiat currencies because any emergency needs that arises can also be sorted out in Fiats currency.
