Selling Bitcoin for the gain of life is a natural thing, and not a stupid decision due to the fact that each person has many different needs and emergencies.
Selling bitcoin today is not a clever decision and not stupid because you will still receive a money through it but not that big but it is enough for your needs. I still suggest if you hold your bitcoin and wait for the right time when the price raise and where it is higher enough than the capital that you invest in it. Also when the price decrease it is the right time to buy a crypto, be wise enough before you regret what ou did.
