Why bitcoin will not work as a day to day currency

Unless and until bitcoin reaches stability, it cannot be a viable option for day to day use.

Imagine buying an XBOX from a online shop which accepts bitcoin for 0.3 BTC assuming its USD equivalent is $800.

Now, due to its volatile nature, 0.3 BTC could be equal to $1000 the next day or $300.

How will a business operate will such volatility?

If we assume, the price of bitcoin will never go down. Why would anyone want to spend such asset on a day to day transaction?

This makes me think, where would we use bitcoin. Now don’t tell me what blockchain is. I very well know the differences between these 2.
