Wouldn't it be better to donate BTC? If gnosis wants to use donations for expenses, BTC would be better. If the donated ANC end up on the market, it will create a lot of unnecessary sell pressure.
Assuming 4000 ANC, it's not much and will not cause significant selling pressure. I have put up a buy order for 5000+ right now at 0.0017.
Also the way this pump is going we are on track to reach $1 parity in the next couple days anyways. At current prices only 3480 ANC is needed.
