I am hearing about this argument for so long. A lot of people claim that no one will use Bitcoin as a currency, if it's value goes up almost constantly. I don't think that is the case and in fact I would say it is one of the plus points of Bitcoin. Let's take an example, where you need to do some shopping and pay utility bills. You need $300 in total to do this. Now this expenses are spread out over several weeks.
If you want to pay using fiat currency, then you need to store this much amount in the bank account and make the payment when they are due. The exchange rates will remain constant. On the other hand, if you store this money in the form of Bitcoin, then there is a good chance that by the time you make the payment, your initial $300 might have grown to $330 or even $360. So overall, it is beneficial for the user.
Indeed, based on your explanation, making payments using Bitcoin will be more profitable than making payments with fiat. Because the price of
Bitcoin is likely to rise, while fiat will remain. But it will be useful if the price of Bitcoin goes up, what if the price goes down. We also need to think
about the worst that will happen, so with Bitcoin's volatile price, many people still choose fiat to pay the bills. I also still choose to use Bitcoin as
a digital asset, the reason is because the price of Bitcoin is volatile, it is too risky to use Bitcoin as payment.
