there are some folks that sold their bitcoin when the prices drop to the range of $78k recently because of some certain expenses they wanna take care of and this is where emergency funds are needed because with it you be able to hold your bitcoin as long as you can, even when there might be some expenses you be able to handle them without tampering with your bitcoin investment.
What a pity, I mean for dudes that has their backup funds locked in Bitcoin and had to sell at a loss to meet up with demands. I think gold should consider having their backup funds in Fiat or stablecoins at least, there's no need gambling with these survival funds but locking them in Bitcoin for sharp interests to further boost it's value. Bitcoin is very volatile and you can't predict the price correction that might meet you when you want to put those funds back in use.
Guys that aren't building their emergency funds alongside their Bitcoin accumulation are already on the wrong discipline in their accumulation journey and when those emergencies arrive, they tend to indulge in even greater wrong by tampering with their portfolio before maturity. The effectiveness of our backup funds can never be overemphasized. Your portfolio is never safe without their presence
