I have been trying hard to send the donation for the last two days but I was unable to send it due to an error in the monero address. But I later analyzed there was a mistake that was causing this problem so I was able to resolve it now. There was a bug that caused invalid addresses to show up when sending donations, however I have now resolved this and now I will be able to send donations. For those who are unable to send donations due to high transaction fees in Bitcoin and Ethereum, you can do transactions in Monero where the transaction fees are relatively low.
