It's interesting that you can look up his donation address in the block chain https://blockchain.info/address/1CPKAMtD4bcLrh8SRHfSxBBMmQQ5cqahPZ and see that he has received 199 BTC, which is almost 2500 USD at the current exchange rate. He has probably received even more via traditional payment methods, so he should have at least 5000 EUR already.
