38 BTC is currently more than $23.000 I guess some rich BTC whale must had a good day or something.
We need more serious bitcoin donation projects. But I think that anonymity of bitcoin donation is not that great asset here, since most people donate money to show off anyway.
The problem with certain donation sites is that people with scam intentions can create a professional looking site with a bit of marketing to it, and scoop up great amounts of coins in name of a charity that they are not, and no one will find them. It may sound a bit harsh for certain charities with good intentions that aren't officially registered, but people at all times should only focus on registered charities when they are out to donate some bits.
