If I had any.....I wouldnt sell them
Why don't you have any? Did you just hear about bitcoin?
You can start to buy $20 a week or some other amount that is reasonable and manageable for your budget, and after a while you will accumulate more and more bitcoin.
I know that some people have very tight budgets, so frequently it can be difficult to stock away a bit of savings and investment, but it is a good habit, once you identify a place in which you do not mind storing some value and think long term about such investment (and having your other living expenses and emergency expenses stored in other places), whether long term thinking for you is 5 years, 10 years, 30 years or some other timeline.
Even if you are thinking long term, you are not necessarily locked into such investment choices that you make now, if in the future, you were to reassess your current investment decision in bitcoin to be better placed somewhere else, then you can adjust in the future as you might become aware of some other strategy that might be better suited towards yourself, your situation and your views.
