Sure.
"Remotely send money" is a super hard thing to do. I literally just struggled for a month with a transfer that included 3 countries, none of them is English speaking. It required letters from banks, accountants, plenty of forms of different countries, translations, stuff which is lost in translation (the bank was unhappy with the word selection of a non-English speaker accountant, for example), different formats, different standards and navigating countless options and tricks in order to avoid ridiculous exchange and transfer fees.
This was for a "simple" action in the real world, involving me and a regular seller of something. Now take this and try to divide donations between 5 participants of your project, each from a different country and a different language. Good luck with that.
Hwoever, in my open source project we did the same thing in 20 seconds with crypto. Not because we avoid tax (we don't), but because the international mechanism is cumbersome and inaccessible if you're not an expert, and expensive probably even if you are.
We manage the donations/profits with votings, and are not familiar with a platform offering a safe way to do that in our settings.
Besides, my experience with platforms for open source projects (or in general) is bad. There is no one platform offering all the services we need, so we end up having dozens of accounts (which is actually a source of tension, because when you offer to use a new platform, an argument starts with those who "have enough accounts in their life"). Moreover, platforms eventually close, so you get stuck (migration is a hard thing to do).
Let me ask a question that maybe will look at it from a different angle. Which problems remotely sending money and online platforms solve that crypto has for managing votings and finance of an international online open source project? Seems to me it beings 100% extra problems and 0% solutions.
