* There is one hardcore bitcoin view that sees it as a currency that provides financial sovereignty and people with this view don't care about the price fluctuations at all.
I'm seeing bitcoin this way too, but I have to admit that it's annoying to buy stuff in different exchange rates each time. At the moment, in order to avoid this I can make a time deposit for gift cards so I can have all my purchases in the same price. You obviously can't do this if you don't have enough liquidity and must be aware for the gift cards' expiration date.
* Another more mellow view is those who spend bitcoin while enjoying the increase in their purchasing power. For example you have $100 and park it in bitcoin then after some months you have $200 to spend. Who doesn't like that?
The one who also dislikes having $50 instead of $100. Fortunately, these highly fluctuating times have gone. It's way calmer now.
This is why despite all the slow adoption we are still seeing great progress in adoption to the point that I have even seen restaurants that accept bitcoin payment in where I live!
I wish this happens to me too. It'll feel great to pay my fast food deliveries via lightning instead of cash.
