I personally refrain from purchasing things using Bitcoin because when I do, after a while the price increases so tremendously and I regret having bought that item, turning out to be way more expensive.
I felt that really well when I bought a pair of $250 headphones for 0.4BTC, which is now worth over $3000.
If your fiat budget was $250 for the item and you converted it to BTC to pay for a item, how much did you lose {of your own money}? Let's say
the price dropped 800% below the price you bought it at... ....You would have been in the clouds. Also, let's say you bought $250 worth of
bitcoins a year ago and the price increase was 800%. {You would have been buying that item with your profits and not your initial investment.
