Well, they say that it's only good for bigger amounts but you're getting there soon if you also accumulate as you hold, you should have the goal of increasing the amount of bitcoin that you want to hold.
I agree with you. Bitcoin has been really increasing its value over the time, so holding it especially for long-term goal is a good idea, in my opinion. But if OP would have to really sell, I suggest to not entirely sell all of his Bitcoin, and try to buy again if the situation permits him to do so. I think that he’ll never regret holding even for a long prior of time since we have seen what Bitcoin could give after some time.
It's always the balance of your situation, if selling will make your situation better during the tough times, you sell but it's advisable that don't all that you have.
