WCK is one of the best run charities providing food in otherwise hopeless catastrophes and wars. https://thegivingblock.com/donate/world-central-kitchen/

At least a few that I know, actually! Example: https://msf.org.au/donate/crypto

Hopefully every well-managed one.

Regardless what your views on Bitcoin are, accepting donations of appreciated assets just makes a lot of sense from a tax optimization perspective: The donor gets a write-off of the current market value, while the (nonprofit) charity can sell the appreciated assets without incurring capital gains or income tax.

At least that’s the case for stock donations in the US.

All of them after you convert it into fiat through an exchange.

Hopefully before, since otherwise you might end up paying a totally avoidable tax bill.

All charities do if you open a Fidelity Charitable account and fund it with Bitcoin. :)

In the US it is tax adventitious to donate appreciated assets, including Bitcoin. (or even especially bitcoin as few other assets have appreciated as much)

It's often not highly promoted-- usually posed on an 'other ways to give' catch-all as it appears to have a slightly negative effect on conversion rates (I've heard there is some evidence that accepting bitcoin sends prospective donors off on a rabbit hole of learning about Bitcoin).
