Yes.
What I like to do though, is that every time I spend some bitcoin, I also buy bitcoin with fiat, at least the same amount, usually more.
So, by using this technique, I am actually increasing the amount of bitcoin that I have every time that I buy something with bitcoin. Win/Win.
Spending isnt bad as long you do able to accumulate more than back! So its up to someone on how they would really be doing it because spending nor accumulating is on someones preference and of course it is on someones financial capacity. Spending on various useless things
is such a waste thats why you should really be mindful on how you would spend it or simply hold it for the future.
