I think it depends on where you stand in this matter, if you are a bitcoin investor maybe you need to hold bitcoin for a long time in the process of taking profits, I think that we also have nothing wrong with using bitcoin or spending it on what we want or use bitcoin as a transaction tool like fiat that you use for your business or as a transaction tool in your business.
To be honest, like what I mentioned at the beginning, it depends on where you stand in treating the bitcoins that you have, but I think if you are looking for a better place between these two functions, it is to benefit from investing in bitcoins, in my opinion.
