If someone can tell me what altcurex can offer that cryptsy, poloniex, mintpal, coinedup, coinex, coins-e, and all the other exchanges don't, then I'll shut up and trust the devs. But seriously, what is special about yet another exchange, and why should microcoin have anything to do with it, other than being listed on it? It just seems that there's now a conflict of interest between the coin and the dev's new project.
Have you seen the demo video? It may not offer anything "new" per say, but it sure as heck looks a lot better and professionally done that coined up, poloniex, coinex, and imo, even better than cryptsy. That alone will make people come to that exchange. Plus, if thye can get other comoodities besides crypto currencies, like USD, EURO, etc. that's a huge leg up from the other exchanges.
How the exchange will benefit Mirco Coin, idk, but I would assume it would if they can create a MRC/USD trade option.
Still, I do agree with you that Micro Coin needs to be marketed much better than it is now. Marketing is pretty much non-existent, which is not good for the long-term value of the coin. We need a market place like Noble Coin has set up themselves where people are purchasing Amazon, Newegg, and other gift cards with Noble Coins.
We also need a good website with good graphics and logos to promote this coin. We need giveaways. Unfortunately, this requires talented people, which is also why the dev should set up a bounty.
