The idea of selling your belongings especially those who are not actually beneficial anymore can be a good option. We can raise funds and save the emergency. But if its not enough yet, then probably I won't hesitate to sell my bitcoin as my last resort, otherwise going for another debt only means another burden.
There is no race in buying and holding bitcoin, so I just delay my bitcoin investment. Emergencies need to be attend as soon as possible, and I don't see any wrong selling my bitcoin, especially if only a portion of it is needed to save the emergency.
Selling off a portion of my Bitcoin isn't a bad idea but it's only bad to me, if I just only started and not gone as far into or close to a decade which makes it a long term investment according to my own understanding and reason for investing in Bitcoin.
Also, borrowing may be a good idea if I have a steady source of multiple source of income and then I can delay continuous investment in Bitcoin at that moment until the cloud is clear.
Lastly, to sell my personal belongings to make up for what I lack is dependent on the kind of belonging. The question is, does such belonging belong to the class of an asset or it's just a liability that isn't worth much in the possible future? The answer to this question will determine my next best course of action.
