Just setup the donation on librepay! Though I'll say that I feel a bit uneasy that it doesn't have 2fa. Do you think setting up opencollective might be a feasible thing or should I maybe look at getting a disposable debit card for librepay?
I looked into opencollective and it's a bit more involved than liberapay. I think I'd have to register as a 501c3. I would just set up a strong password with Bitwarden or similar.
