Those people who do not touch their BTC are investors and use Bitcoin as a tradeable asset and not as currency. Obviously, they will feel bad if they are forced to use their investment due to a lack of fiat currency funds. But for those who look at Bitcoin as a currency, will be happy to find merchants where they can pay in BTC. I am one of these kinds of people that don't feel bad paying with BTC.
The true function of Bitcoin, as @serjent05 aptly stated, is that it serves as a digital currency that enables peer-to-peer transactions without the need for intermediaries such as banks. However, Bitcoin attracts individuals with diverse objectives. Some consider it as the best long-term investment, while others view it as a speculative model with high profit potential, and some employ it solely for transactions, among other purposes. This multiplicity of functions is a significant advantage for Bitcoin's existence since one asset can have multiple functions depending on the owner's perspective.
Transacting with Bitcoin is seamless as it offers security, anonymity, low transaction fees, fast transaction speed, and decentralization. These features are unmatched when compared to bank transactions.
When determining your perspective on the future of Bitcoin, consistency is key. There is nothing wrong with adhering to your chosen perspective.
