Practice can bring a lot of improvements, and sometimes it could take a few years to really start to get used to how aggressive a person might be able to be without becoming overly aggressive in terms of how much to invest in bitcoin, how much to use for expenses and how much to keep in some other kinds of emergency funds that might not be linked to the price of bitcoin, but instead linked to the fiat currency in which expense might be accounted,
JayJuanGee, what you say is certainly highly recommended for any investor. I believe each of them need not put their budget 100% on bitcoin without diversifying their budget elsewhere. Even having some fiat reserves is recommended so that when they need money they don't have to ruin their long term investment plans. In the case of buy on dip and hold, selling bitcoins at a time of urgency should be avoided, so to be sure, adjusting or diversifying the budget is required. The emergency fund is mandatory instead of continuously growing the investment portfolio.
My guess is anyone who has an investment in bitcoin without having an emergency fund in fiat, then sooner or later they will sell their bitcoin. At least 20% - 40% of the total investment budget must be saved as an emergency fund, this will definitely help them if an emergency occurs.
