The post you're replying to is about Bitcoin being "used", not specifically "used for everyday transactions". Bitcoin has so far been a decent asset to hold as a store of value if you don't want to or can't store your money in the traditional financial system. Lots of everyday people in countries with high inflation or strict controls or how people can store money hold Bitcoin (or perhaps more commonly, stablecoins) for a very practical purpose other than speculation.
Bitcoin has only failed so far as a replacement for Visa and Mastercard. So no, nobody's using it to buy coffee.
