Your point per discipline is inevitable when it comes to investment in general mostly the most valuable like that if Bitcoin, but my point of argument or opinion remain that if what emergency fund can't not resolve because there is not amount of fund that can take care of unforseen circumstances like life threatening, if you have not seen heavy investors hit with life threatening who sold their properties and many belongings even seek public contribution inorder to save their life I I have witnessed even hear some through news or Media sorry to use this common example of a Nigeria actor who was hit with illness that leads to amputation of his leg the man called john okafor popularly known as Mr ibu , the public made some donation and he lost his life if such a person has Bitcoin as asset and selling it could save his life you think he will reserve it and died because of long time holding, when I said life threatening it really entails life issue with deep sense of details. Sorry to use the particular scenario assuming a man kept emergency fund that is not up to what a kidnapper who adopted him is looking for and no means to get the demand, you mean such person should die and leave the Bitcoin unsold if he practice Long holding where means of selling and get released can be made, for me it's unwise.
If that is not possible, you should think of any landed properties to sell to raise the money. If there is no property to sell, and there is no other way to get a loan from bank or friends and relatives, you can take money from your business account, that's why multiple sources of income are encouraged for all investors. When other options are exhausted and no way to raise the money, then you can think of disposing your bitcoin to save your life. The point is this, your bitcoin should be the last option of raising funds if you find yourself in situations like that. You should not rush and dispose your bitcoin without trying to raise money from other sources first, even though health ground is a good reason to dispose your bitcoin investment premature.
This is just bullshit , I know holding Bitcoin for long is a prior when comes to been a Bitcoin investor, but the fact still remains that your health should be put first , your emergency funds was not enough to coverup such emergency ( life threatening) and you have some Bitcoin stash that you can run to when comes to the worse . Is not everyone that have properties or people to run to mate and I won't advice carrying loan to solve such issue , because you are endangering your health more because I believe with that loan you won't be able to have any peace of mind, imagine someone that just survived a life threatening event, don't have any peace mind due to thinking on he or she can pay back such loan .
The best to do is to sell from that Bitcoin to handle such emergency, because a dead man can't accummulate Bitcoin , but with time you can be able to replace the amount of bitcoin you sold back but not at same price rate but doesn't matter aslong you where able to handle that emergency, because we should know how to differenciate need from want , always prior your health, doesn't mean you will start tampering with bitcoin in any slight expenses.
