I def agree. V4V has a bright future
I would also say that time is another indicator of value exchange. Arguably more valuable than bitcoin in some cases. Sats also have the issue of relative 'value' to both the donor and receiver, ie a billionaire receiver may not value a 10k zap but the donor sees it as a reasonable sum of money. Does this mean the post is less valuable?
On the other hand time is more or less the same for all of us.
A well thought out response indicates the person has spent time on engaging and this is also very valuable. I love sats but feel like an artist for example might value someone really admiring and discussing their work versus a 20 dollar donation in the box. Not a hard and fast rule, just a consideration
Just my 2 sats
