How many people in your neighborhood where you live hold or use Bitcoin, probably close to zero. And how many in your own family has recently paid for anything with BTC?
The point is that Bitcoin failed because only a few of us use it? It looks to me that it works exactly as planned.
In your neighbourhood how many people have heard of Bitcoin? Probably everybody as in mine. Even my grandma knows of Bitcoin. The fact they haven't used Bitcoin yet doesn't mean they won't use it later and that Bitcoin has failed. Tell the people that buy Bitcoin in Venezuela, Lebanon, and Turkey if they prefer their wage in their fiat currency or in Bitcoin.
