No. Be a idealist. We need more idealists. Life is not worth living if you aren't one.
Often people will give advice that tells you to follow existing marketing demand.
That sounds very wise and common sense, but often (specially for a thing like Nostr and Bitcoin) it's merely status quo bias turned into reasonably sounding words.
Bitcoin had zero demand when Satoshi created it.
Bitcoin is not a tool, Bitcoin is a dream that we have to struggle to make real.
If it was just a tool it would be a very stupid and useless tool and not worth mentioning or thinking about ever.
