Bitcoin is like a Rickenbacker electric guitar:
It was the first of it's kind and it costs more than most of it's competitors. Also, just like bitcoin, almost immediately others began to make improvements, and now everyone owns a Gibson, a Fender (or a knock off) and almost no one owns a Rickenbacker, and nobody bothers making knock offs.
But, just like a knock off, Bitcoin has it's Lightning Network, it sounds fast and slick but functions like an Edsel.
