The problem with tipping bitcoin is that you have to explain so much to pre-coiners that in my experience, 99% won't claim the tip. I ended up adding instructions and disclaimers about the tip expiring so I could claw it back after 3 months. I didn't claw it back in years but seeing 99% not getting claimed is really frustrating. But it was a touch point for those people, most of which I only saw once in my life, so I will never know.
