Thanks
Don't you think a new algo will drive miners away from the coin. As it gets difficult for a new miner to start with new tools. Just wondering. I want it to be easier for miners.
There's a certain trade off you have to make. Using a less used algo you tend to attract more of a niche audience, those willing to mine the coin because it's slightly different.
Going the scrypt route means if there's a hint at the coin being profitable you'll become part of the multipool's rotation and see network hashrate spikes of 20-30 ghash.
Right now, alternative algos generally means a more stable network hashrate with miners that intentionally chose to mine the coin, rather than users oblivious to what they're mining through a multipool.
edit: Not saying sha3 is necessarily the way to go though. Adaptive-N-factor scrypt is quite funky as well. Take a look at Vertcoin which is doing quite well.
Should sha3 become popular, it is one of those algos that is very easily to create bitcoin-like ASICs for.
Unlike adapative-n scrypt, partly because of scrypt already being harder to do on custom hardware and due to how it changes over time (the adaptive-n-factor part)
