Right now they are similiar however curecoin has 2 methods of mining at once sha256 and the folding miners. With curecoin those giving the network security do not benefit folding projects. They are also less likely to continue supporting the network once mining becomes less profitable. You can't feel as good just giving network security as say finding a cure for cancer. Those miners will drop off as soon as there's no money to be made causing a less secure network and higher likelihood of a fork. I feel that gridcoin has an advantage because of this. Also the new wallet looks amazing. Next gen stuff. More advanced than nearly any other coin.

What gridcoin really needs is an effective marketing program. Currently curecoin is winning in that department. I truly hope both of them become the most successful coins. It perplexes me how so many seem so interested in all the shitcoins than the ones that truly make a difference.
