Personally, I really appreciate with your effort and UNICEF France to accept donations in BTC and cryptocurrencies (ETH / ERC 20 Tokens). It seems UNICEF giving a good attention on crypto. This should be a good way to get more donations. Crypto enthusiasts also can participate easily by using BTC or ETH (ERC 20).

By the way, I see it is not first time UNICEF utilizes cryptocurrency for donation. At least, I read it in some articles:
