I liked the idea of gridcoin, but it was executed badly. My main cons were: unprofessional start, in the first months the dev doesn't care about cheating and the main problem: The (GRC boinc-)mining is bound to Scrypt, which means that you can get GRC only if you have also a decent Scrypt miner (and in times of Scrypt-ASICs, this will favour only a few people with money).
Nice to see that Curecoin went a much better way: The mining and folding are completely separated and the start was much more professional (except for the unfortunate investor phase which I'm still very unhappy with).
Thanks and please keep up the good work.
