Absolutely correct and I hope many investors would understand this and stop investing all they have on Bitcoin without left over that can be used to take care of emergency bills that might come unexpectedly. Being a crypto investor is not all about buying and holding Bitcoin for as long as possible but making sure that their are funds ability Incase we find ourselves in circumstances that needed fund to keep us safe and out of reproach that could make us a laughing stock.
There is what we call discretionary income, as an investor you should figure this out of your income, there is also emergency funds which I believe that all investors understands that emergency funds are primarily funds set aside to tackle emergency which are unexpected occurrence why you are going about your investment, this emergency funds should be on its separate place and as investor don't ever think if making use of this for investment purpose because this fund is what will help you not to rely on your investment for solving emergency needs.
This is the reason why every investor should make sure the weigh their income, share it evenly in different parts, the investment should be on it own and tat should be when you might have making provisions for everything, they emergency funds well kept then you can invest with the remaining funds which is now the discretionary income, this discretionary might be huge amount because it depends on the investor's income daily, weekly monthly.
