Selling bitcoin would only be wise when you really need money. Having bitcoin is having a good kind of asset, there is no like bitcoin that can appreciate in value at an instant. As long as you can keep your bitcoin at any cost, it is the wisest thing to do. Prefer to hold tha to spend it, in no time.you will see the fruit of your waiting and investment.
It might not be a problem to sell bitcoin if you need money dude, but some users sell their bitcoins because they panic with the
current worrisome price rate, maybe it's a stupid choice, because if you want to restrain/holding you do not have to lose like that..
