It's very difficult to dispute your assertions that Bitcoin currently provides very little utility outside niche markets, that a lot of the investments being made are laughable, and that the shifting goalposts phenomenon is in full effect.

But remember, a lot of things we use the internet and mobile phones for today were envisioned and promised in the late 90s but failed to materialize in a practical, mainstream way until very recently, over a decade later.

Who knows what cryptocurrencies, or the concepts behind them, will mean in another 5, 10, or 20 years. Maybe nothing, maybe a lot. It's still too early to tell.

(I'm skeptical myself, especially in actual currency applications, but open minded.)
