The "real value" is in the name, stability; people quickly stopped using Bitcoin for buying pizzas because its value was so unpredictable, making it more suitable for an investment than a currency, which made its value even more unpredictable because it wasn't spent predictably anymore. Like, there was a webshop that accepted BTC, doing real-time ish price conversion between USD and BTC; if I was that webshop, I wouldn't have sold the BTC for fiat as it came in, but just let it accumulate until the BTC price went up favorably. A $100 purchase would become $200 with the BTC price appreciation over time. Anyway yeah. Killer use case is a digital currency whose value is stable and predictable, so actually usable as a digital currency.
