Hmm, not been in one for a while, but I’m sure most mosques and temples would be grateful for any funds you can spare… though most will pay out of their own funds to support those who need help. Would be a sight to see an XMR addy etched into the collection plate in a Catholic Church, tho, ngl.
Have seen churches with an computer at the entrance, where you could spend some money using your credit card. They probably even accept PayPal. So accepting crypto would be the next logical step to take.
