Possibly add a Venmo link (more people have that.)
Also, since GoFundMe would take it down, you could use the other similar service that Project Veritas used after the one whistle-blower's GoFundMe got frozen. (Not sure what it is.) Maybe also look at what service Kyle Rittenhouse used, because I doubt that was GoFundMe.
Probably quite a few would donate, but only a bitcoin link kind of limits.
