Your options should be in this order, selling your Bitcoin, selling your belongings, and then borrowing.
Selling your Bitcoin should be first on your list because, for me, your BTC investment can also serve as an emergency fund. It's like money in your savings account, you can withdraw or sell it whenever you need it.
As for the second option, of course, things like jewelry can also be sold to raise additional funds. Jewelry can also be considered an investment.
As for the last option, borrowing should be your last resort if you don't have the first two options. I'm not against borrowing, especially if you have the ability to pay it back. Otherwise, you'll just end up creating another problem later on. It's only a temporary solution.
I do not think there is one rule for everyone. Whether you should sell your Bitcoin or borrow money to deal with an emergency depend on the situation.
If the loan has a low or zero interest rate and you are perfectly capable of repaying it on time, borrowing money is not necessarily a bad option. If the loan is too expensive or put too much pressure on your finances, selling a portion of your Bitcoin might be a better option.
There is no fixed order that works for everyone. The decision will depend on the financial situation, the cost of the loan, and the urgency of the problem to be solved.
