Whitelist:

* Androidstokens: Still alive despite everything that was thrown at it, I'll bet the dev spent more keeping this coin alive than was spent on any other coin out there. Popular both in the western and eastern markets. If anything, we can be sure the current dev will never let this coin die as long as he can help it.
* PMC: A worthy experiment of the future of BitCoin, has already found bugs (block reward resets to 50 after last halving) in the BitCoin code that would have gone undetected until it was mined out otherwise. Widely distributed, serious community, Android wallet with more features than the one that everyone keeps cloning. Developer here
* DataCoin: Truly innovative, in the sense that it expands a feature like NameCoin (domain name lookup) to more media types for perpetual distributed data storage.
* GridCoin: Truly innovative, in the sense that it rewards people spending electricity on generally altruistic BOiNC projects in the form of crypto.
