After giving it some thought I think I’ve come around on the lightning bolt. It looks like an s, and electricity is decidedly more cyberpunk and badass than any other option.

When I created the poll I didn’t know people used the lightning bolt for Sats I thought it meant distinctly LN, but it can do both.

Wish I could update my poll. Also the tip icons on this site should go the same direction as the ⚡️emoji.

The stacked symbol is still great and a close second for me but lightning bolt works well and already has shades of adoption.
