Well considering the rate at which fiat and paper currencies are disappointing, bitcoin seems a good option, but even bitcoin is affected by price volatility, it would be a perfect fit if it is a stable coin, my opinion though
Bitcoin is affected by volatility positively and negatively. If it is stable, I don't think we will be seeing this price right now. As a decentralized crypto currency, being volatile is normal but I do respect your opinion since for you that is the ideal bitcoin that might be the ideal currency in the future. As long as most of the people here look at it as a speculative asset, I don't think it will never be used as a currency.
