I think you guys are missing the point. Anyone who wants to mine (and knows how to do it) can mine the good old way with a standard qt miner. People can and will start mining pools etc and mine Neucoin just like any other PoS coin. Even PoW actually in the first year.

No one has to sign up for any growth accounts. In fact, if you know how to mine why would you? Just mine they way you normally do.

But you forget how insanely technical mining is for 99.99% of the population. There are VERY FEW people who know what this means, let alone how to do it, or that would ever want to have to learn. That's who the growth accounts are for.

Neucoin is going after consumers, not miners and speculators. Sure, they need miners and speculators too - but their whole idea is to get lots of consumers.
And consumers will never download a client. Never, ever, ever. They don't know anything about computers or blockchains. They don't know about mining. Just as they don't know much about bitcoin. Or will ever download a client or even join a mining pool. They just want to click something on their phone.

But if these consumers earns some free coins by playing a game, and if there's an easy way to just click right there on their phone and those coins start to multiply so that he can play even more games, they may think it's cool.

So, the growth accounts isn't the only way you can mine Neucoin. Again, if you know how to mine, just mine. The growth accounts isn't for us here on bitcointalk, it's just a consumer feature for the facebook mainstream who has never even heard of "cryptocurrency". And for them it's pretty great, drop and drag and your coins are multiplying. They key here is easy and fun. That's all the facebook masses care about.
