Like many people have already said, investment fund should be separated from funds for basic needs thereafter emergency funds should also be kept for optimal management of the investment portfolio. This way there will be no pressures to sell even if the price drop because there is the confidence that Bitcoin will always recover with time.
I agree.
Because what happens when your entire investment like if you're holding Bitcoin is your entire wealth, there is a big tendency that you will be forced to sell it at a time that you're not willing to sell but you have to.
That's why when we invest, make sure that we've got funds as well like emergency funds or extra funds that will be touched and protect our assets like in Bitcoin if unforeseen times comes.
