I am afraid I have very little knowledge about bitcoin except that it grows faster than any currency and scalability is a serious issue. Reddit once deliberated on turning reddit karma into a crypto but backed out later. So it's not really an innovative idea, but yes, first implementation yet. As I said I am a dumbo about crypto but I have a question: if someone is sending sats via nostr, who is minng them? And why send coins to internet strangers? For funny memes? Am I missing something? #asknostr

As @QW mentioned there is a lot to unpack in what you said. Both @QW and @Derek Ross already mentioned a lot of the benefits of Bitcoin so I'll concentrate on offering insight into your last question. In some ways you could say the same thing about anything else in life such as life advice. Just because you can get something for free, doesn't mean it has no value. The thing with #zaps is that there are no rules and that's the beauty of it too. It becomes a free market dynamic where anyone can decide what they think something else is worth through a one-way public benevolent act. Like kickstarter but on a very granular level.
