If you have a clear reason why you should sell your bitcoins in the past, then I don't think it's a bad decision.
There are many reasons to sell bitcoin holdings and one of them is when you feel you need the money urgently. Your health and anything other like building a business are some of the reasons to sell bitcoin, but if you have better options then holding and seeking a solution such as a loan is fine too.
Bitcoin's priority scale is not more valuable when you experience health problems, selling Bitcoin for health costs is not too bad for me and even if you sell Bitcoin as a business support is far more productive because when the business is developing you can buy bitcoin with a much bigger amount. But there are other ways that can be taken, namely making financial scale to meet other needs, such as health, children's education costs and costs for businesses that have been prepared.
Sometimes the conditions for the need for money are not in the right conditions where the price of bitcoin has decreased, so selling the bitcoins that we have at that time will make a loss. Preparing needs that are used through savings is also needed as an option when we need money suddenly and don't need to sell bitcoin when facing conditions like that.
