This is a textbook use-case for crypto. And honestly, you can fundraise for a lot of things through those conventional channels right now anyway; freedom of association is still strong in the West.

The trick is always getting people to send you money in the first place.

If I remember correctly, this one of the use cases why bitcoin was created in the first place. It's not anonymous but it does solve the control problem.

The only other way I know if is cash via sneakernet. Also not completely anonymous, and it could get you labeled a drug dealer or distributor. Especially in the US.

As for how to get into bitcoin, you can mine it, but more feasibly, just start doing commerce in it. If you have a podcast or you stream, accept lightning boosts. Or you could sell off your old things for bitcoin. If you have some other business start accepting bitcoin as a form of payment.

If you need to convert a national currency to bitcoin there is a peer to peer network that accepts cash, as well as several online exchanges (ID usually required, at least in the US.

As a warning, once you step off the garden path you lose it's protections, so buyer beware. The "Big Money" have a vested interest in minimizing how badly you can get screwed in their system. Such protections don't exist it the alternative currency sphere regardless of which crypto currency you choose.

Your options are XMR(monero), cash or barter. Or hawala as the other poster described here, but I do not know much about that.

Does anyone have any idea why this is being downvoted? I'm not hurt or anything, just curious.
