>I'm a Bitcoin supporter, but one has to think there are useful hard problems to solve rather than just banging out SHA-256 hashes over and over. If that's true at all, then Bitcoin is wasteful. There are curecoin and gridcoin, which base a large portion of mining profits off Boinc credits. Kinda defeats the point of being decentralized though...
