They should set aside some money then put it on their emergency funds so that they would have some sort of security if there's financial issues or other trouble came. Sine if it happens that they put all their discretionary income on Bitcoin itself once they face serious issues they provably don't have a choice but to dump their Bitcoin. Also it will be so bad if we are in bearish market situation since they would sell it at lose.
So they should think about what's will come in future so plan your investment and other thing that can secured our selves since its not good to be aggressive especially if we are not fully prepared on future challenges that might come to us.
That's what is feared, because someone could panic and sell their Bitcoin holdings because they don't have a backup of money for their financial needs in an emergency.
So there is no other option but to sell some of the Bitcoin that is held.
It's hard to deal with emergencies like this, but by doing the right management at the beginning before investing is done,
there's no longer any reason to start selling Bitcoin at a low price due to the financial emergency.
Good management and bears will provide security to the main investments in crypto and then provide flexibility to the reserves that have already been made,
that way everything will be safe, and the investment will continue as planned.
