it is funny when you see some people (in general, not talking about OP) insist that bitcoin can not be used as a currency because its price is too volatile and as soon as the price becomes stable (like the past 3 months) they forget what they said and start complaining about why price is not going up and call the stable price a bear market.
This how crypto jeets always think because they are buying Bitcoin for a quick gain only and nothing more. I never experienced Bitcoin is stable because it never peg its price on a certain price point but since you already brought up Bitcoin currency, Bitcoin is really hard to become a currency because it need to always tie up the value in fiat just to determine it’s price. People need to check the conversion rate first before they assign the item value or transaction amount in BTC to determine the right fiat value since it’s value has no determine price point.
