I am asking about cpu based mining method.

I understand your question; however, it is very difficult to keep miners from attempting to corner the market. I won't go into the specifics of a game theory discussion focused on the economics; rather, I'll say this: most projects don't care how they get their hashpower up, they just want participation. Few projects have the magical property of common sense that requires them to keep hashpower low in the early days in order to enable and encourage CPU mining. Our project, bitcoinR.org kept hashpower low by not doing a wide announcement immediately. This was our best shot at creating a global distributed network of actual people instead of corporations.

By keeping the threshold lower, we were able to get some very loyal miners who mined the coin early. In fact, I believe one can still mine the coin via CPU assuming that their system is quick enough; though it seems that we are inching toward the GPU phase of the mining evolution. Once the pool software is released, the hashpower will concentrate a bit but the desire to mine the coin spreads exponentially.

This is more prevalent as exchanges pick up the coin and assign a value based upon supply and demand; then, there is an economic function where the price of the coin will tend to gravitate to its production cost. It's at this point where we will come in and make an attempt to stabilize the price in line with our whitepaper.

Long story short, pay close attention to Twitter, Reddit and here at BT for announcement threads. Don't look to people that have thousands or millions of followers, look for the ones who have a few hundred, that have credibility outside of the crypto world- get interested in what they are interested in. You'll find projects of value that way.
