My favorite coins are those with a Proof of Work system and no Pre-Mine. In my opinion, No ICO and No Pre-Mine prevent us from pumping and dumping because usually the distribution is fair and no individual or entity holds the largest coin.
It's not even fair, the buyers of coins got nothing for their money and they can get only the coins from the miners. This is also making the network being controlled by the miners. The best thing should be the hybrid system that will let the buyers of tokens participate in the governance too. When there are lots of drama between miners and it will be making so many fork coins like what happened with bitcoin. Ethereum can't fix its scalability problem due to the miners.
This has proven if POW is not so good as people said.
It must be fair if the buyers, holders, and miners were able participating in the governance.
