Would you be willing to use bitcoin on a daily basis to pay bills if there were businesses in your area that accepted bitcoin? I would be skeptical of any bitcoin investor who says they are willing to do that every day when their goal is to get rich from bitcoin.
You can do this, if you have need to do this like how you can use gold for buying things, real estates for example. It's only whether you want to sell your bitcoin when you consider it as a long term investment asset. You will more likely want to hold it as long as possible and only sell it if you need money for something important.
On daily basis, it is less likely to use bitcoins, but you always can use it, because nobody want to use their long term investment asset on daily basis. They know that if they sell their bitcoins, they will have to wait and hope that their repurchasing price would be lower than that, while it can come or never come.
Well, I think when Bitcoin becomes possible for daily use, and I think people will differentiate between spending wallets and saving wallets for Bitcoin. I think the current barrier is the difficulty of making daily purchases because Bitcoin hasn't yet become legal tender, especially in my country. I assume that when that happens, people will choose Bitcoin as a storage device like a bank account, but the difference is that Bitcoin has what is called a "Store of Value", which means Bitcoin can maintain the value of the money we hold, and can even increase in value, unlike fiat which experiences depreciation year after year like in my country. So, I agree with you that we can do that thing, or do anything by using Bitcoin.
