If you are talking about donating after watching a youtube video, may be not. If you are thinking about tipping a street musician on a internet livefeed, may be.

I believe there is a difference between a live performance in front of you and a video online. Live performances on streets tends to reach put to you more because you are there. Live music moves you. While a video in a browser is too distant, doesn't resonate as much.

Getting change out of your pocket is quicky and easy, sending bitcoin is too much hassle. You tend to think about it more, and probably wouldn't send anything.
