It is a very bad practice to invest into bitcoin with your emergency income or fail to build one alongside your accumulation journey. It places your investment at risk of being tampered in the face of real emergencies. Emergency funds are built only to attend to real emergencies and no other purpose.

Of course we wanted to save as much as we can and hold for a long time. But I guess we can reset anytime as well and go back and re-invest. It doesn't mean that you will sell everything maybe just withdraw a small percentage on your stash and then try to invest that kind of money. It happen to me before, during the height of pandemic as my sister got hospitalized not due to covid but because of other illness, but she eventually died  . So I have to withdraw from my holdings and never think twice to do it to help here with hospital bills. And then I just restarted again. Just check how many weeks or years I need to do it and the go back with it with that goal to continue to accumulate again.

No matter how aggressive you want to be in your accumulation journey, if you don't follow the right procedures by building your backup funds to protect your bitcoin portfolio, you may not be able to have a successful investment activity since you would be tampering your portfolio every now and then to solve problems that your emergency fund, variances of backup funds and floating cashes would've solved for you if you applied the correct investment practices. You can see that you fell immediately to your holdings as soon as a health emergency came up and had to liquidate your portfolio outrightly without any other option, this is what you get when you don't have backup funds in place. Although there may be scenarios that your backup funds weren't enough to bail you out of the emergency, in that case if there is no other option to get funds, your holdings might bail you out to some extent, then afterwards you can structure out ways to replace what you have depleted from your portfolio while building back your backup funds to handle other pressing matters that may arise in the future.

My condolences for your Sis. Demise, it hurts to loose a loved one.
