I will use it when the price is high. That is the same as selling it but not sell directly. So it will help the usage.
Yeah I think holding it will be good to hold our coins for some time at least till the halving and its better not to spend our coins till we see the higher price.
But it will be still hard to know what will happen with Bitcoin itself and that is the problem.
You have the point, bitcoin spending today is not a very good thing to do. It is good to save more bitcoins today as the halving is on its way.
And if you already earned from the halving then it is a good time now to spend actively.
