Last month I saw a couple of street performers who were really good. I had every intention of tipping them, but didn't have cash on me. They did have a venmo qr, but I don't do venmo.

Now, I really should have gone and got some cash or maybe pestered them about accepting bitcoin, but I didn't. Instead, I just ended up not tipping.

I suspect that internet tipping is the same: there needs to be as little friction as possible. It needs to be so easy that nothing gets in the way of doing it in the exact moment that a reader feels inspired.
