I believe that those of us involved in the field of cryptocurrencies should feel compelled to act in accordance with our ideals and therefore, we should prioritize the accumulation of bitcoins before the accumulation of dollars.
We must always keep in mind that one of the reasons that led to the emergence of cryptocurrencies is the search for alternatives to fiat money, therefore there would be no reason for us to exchange our valuable cryptos for centralized money.
Unfortunately, not everyone and not always follow the ideals and exchange bitcoin for dollars. This is absolutely normal. It would be strange if they didn't.
I don't think we need to see the essence and function of centralization and decentralization, if we are just a trader who is looking for
profit from the price margin, I will sell the altcoin to the dollar or to btc, depending on which rate is higher
