The most frustrating thing about Nano...

I'm constantly seeing people saying Bitcoin, and cryptocurrencies as a whole, will never reach widespread adoption because of slow speeds, high fees, and an inability to scale. And in these conversations, often involving crypto "experts", Nano is \*never\* mentioned. Even when Nano is at the top of the charts, it's completely ignored in these conversations. They often reach the conclusion that a fast, feeless, scalable cryptocurrency will never happen. Why is this? Are these people unaware that Nano exists? Or are they choosing not to discuss it?
