After the various types of adoption that occur today, we sometimes think like this :Why do I use BTC to buy goods or transactions every day if in fact now Bitcoin is more dominant as an asset, isn't the longer I hold it the higher its value?.
We also know that the permissionless nature of bitcoin, it further reinforces that there is no compulsion of the owner to spend bitcoin. So we really can't dictate the use of bitcoin, those who own it have the right to use it for anything. To me most importantly with all the types of adoption that exist, it has shown that Bitcoin is becoming more widely accepted.
One doesn't necessarily just have to use Bitcoin for payments, you can always do both things with it; use it as a payment currency, and then also use it as an asset as long as you can afford to do that, because when it comes to using it as a payment method or currency, you will basically just use the money that you generally use for your expenses but your payment currency will be changed, and then you can also buy and hold Bitcoins, as much as you can based on your financial capabilities.
When it comes to using Bitcoin as a currency for making day-to-day payments, there are both pros and cons of it. The most highlighted one of them is one thing that is both a pro and a con, which is the price volatility. It's a pro because it can make your bitcoins have more value and purchasing power if the market is going up, which means you may have $100 now, but you could have $120 after an hour if the market is going up. Similarly, it could be a con because the same thing can go the other way around; your $100 going to $80.
So this is the biggest reason why most people don't use Bitcoin for regular payments, because you wouldn't want to keep your day-to-day funds in a currency or an asset that also has the possibility of losing value, because that could turn out to be bad, especially for those who do budgeting for everything.
