You can use Revolut to send donations in any currency from any country where Visa & MasterCard are operating and it also supports Apple Pay.
Otherwise, you can use Wise — but it requires you to have an account there as well.
If you still there after beginning of Russian full-scale military aggression against Ukraine and would like to use MIR cards or QIWI Wallet to donate — here's my QIWI Wallet. It's better than paying taxes to the Russian state, right?
You can find my BTC, ETH, LTC & DOGE wallets on this page or simply by looking up @alxdrlitreev on Coinbase Wallet.
