Exactly since you could touch your balances which supposed to be used for holding if you don't have enough emergency funds to use for certain things needed in future. That's why its been discussed that 3 months is already enough and some other say 6 months is fine so that they will be in good shape and nothing will disturb them towards their long term hodl plans.
If they just say that they are here for hodl but they don't do any long term preparation for sure they would fail especially if these people will encounter a huge upset and the market will suddenly experience a bear market condition since provably they would dump their coins to save their asses. For this scenario emergency funds is really needed so that they will not think about touching anything then can afford or able to forget the funds they saved.
At least 3 months of emergency funds are enough, there are also 6 months then this is better at least you are safe when there is an urgent need because with 6 months of funds of course there is still a remainder you will also not worry if you have 6 months as a reserve fund. The point is that the greater the funds in reserve you will feel safe and not disturb the investment that is being built.
Yes, someone with unpreparedness, the investment will be a little disturbed, especially if you don't think about emergency funds, you will definitely rely on existing funds, including investment funds that will be sold in the middle of the road due to other unexpected spending needs.
Actually, it's not about the market going down due to bearish that will be sold, because of their unpreparedness with emergency funds, what hurts more is where they don't have an emergency fund while the only existing assets are in BTC at that time the price is bearish, so he loses twice because he sells at a low price, and then he builds an investment in vain.
