For now if someone wants to donate in cryptocurrency they have to donate it Bitcoin. It would be cool if we could also donate in other cryptocurrencies, like Monero. Why Monero? Because it's one of the most private/anonymous cryptocurrencies. And what is GnuPG? GNU PRIVACY guard. So I think Monero users might be interested in donating to the project with their favourite cryptocurrency.

As for the fees, the average fees are a bit higher than Bitcoin ones as you can see in the link below, but I can confirm that (ATTOW) you can send a transaction for $0.77 (price from Kraken):

Also, in the next month there will be a hard fork that will bring 2 big new features to Monero: subaddresses and multisignature. So I expect Monero price to rise in March.
