"Could"... That makes a huge difference. The Minister just says
“I’m not sure every bitcoin player can do it but, anyway, we are open to the discussion. People should be able to make donations through whatever means they want to use”.
.
So it's a "why not".
Anyway, they won't accept Bitcoin directly, Firstly because the donations don't go to the government but to licensed Foundations (there are only 4). So it's going to be one of these foundations that will take the BTC donation. And they will probably use another entity to act on behalf.
Few other charity campaigns started also, like on Binance.Charity and others.
