Yes, normally, if we are choosing to invest in bitcoin, then our two main kinds of back up funds are emergency funds and reserve funds, and of course, we could have other asset that we are invested into that we could draw from or we might have friend/relatives who might be willing to bail us out or to give us a loan, so some folks might have resources outside of their back up funds that they could draw upon prior to having to tap into their bitcoin.
We likely know that we have priorities in what we might draw upon and some kinds of back up funds (such as other investments) are more liquid than others and some are more volatile than others, and there may well be a lot of guys who get into bitcoin, and they have nearly no other assets or resources (perhaps maybe family that might bail them out, but maybe only for small kinds of bailouts), yet the longer that they are building their bitcoin investment and their various back up funds, they may well also be making other investments that could help them if they were to need to get bailed out, so they would also likely have a hierarchy of priority, including that if they end up buying a house they might be reluctant to sell it unless they had no other choice, so if some of their other assets are less liquid than bitcoin, there may well end up being choices to sell bitcoin rather than attempting to liquidate certain assets that are less liquid than bitcoin.
I agree with this. There are some folks that tends to ignore the emergency funds and reserve funds while investing in bitcoin, and as a long-term investors you really need to keep aside your emergency funds for any unexpected emergency that may comes up, some people may think it's not necessary to have it while investing, but the facts is, having emergency funds when investing into bitcoin gives you a protections from being forced to sell off your bitcoin assets. However we are smarter than one another when it comes to financial planning, some investors actually have other business they invested on outside or aside the bitcoin holdings, so whenever any emergency arrives they have plenty options without tempering thier bitcoin assets and these are still the kinds of investors that enjoy taking an advantage of any dips ,because already they have more discretionary income to use, which serves as an opportunity for them to buy more bitcoin and hold for long term period
