Very few people have actual BTC to donate -- this is the big one. Some of those may be holding BTC as an "investment" and may be unwilling to part with it. Depending on how they hold their BTC, there may be significant friction involved in spending it, ie. in almost all cases I expect it's more difficult than entering PayPal or credit card details.

And as you note, it's not like people are super eager to donate using other methods. (And while some might say that a site like TPB, which attracts "freeloaders", is even less likely to get donations, I'm not convinced -- folks might consider TPB both a service worth paying for as well as a cause worth supporting.)

Of course, the upsides remain. It costs you nothing to post a BTC address on a site, especially if you're already handling BTC. There is no interaction with payment providers and all that jazz. There are no immediate fees. Payments are "anonymous" for both sides, with the usual and serious caveats involved in BTC transactions[0].

It's very frictionless to spend it, effectively it acts digitally analogous to cash.

Best way to find out is to try! Generate and post an address here in the next 15-20 and I'd be happy to prove this wrong. (at least from the senders end)

There's lots of friction on spending if it's in an offline wallet.

yes, so don't?

we're talking micro tipping level amounts here, 100 Euros or less stored on any modern smartphone or laptop.
