the devs who holds minereum wants to cash out at high prices
I don't think so, the devs have delivered what they promised, time after time again. Right now they're setting up a company in Switserland to handle the ICO, which can be expected to happen at the end of this month. Also, all the MNE received will be burned, pumping up the MNE price, which indeed is good for the devs, but also for the investors
Not anymore. As you know, the market is growing a lot faster than it can organically handle. We went from 18 billion to 180 billion in less than 8 months, this is an unsustainable growth. This means a lot of less succesful projects will disappear when the next crash hits. People need incentive to buy. A coin that goes up and down and up again is very interesting to investors, it shows an active community and large profit potential.
Every single dev out there is thinking about profit. The use of that product is to generate as much revenue as possible through solving a problem. Also, ART doesn't really target China as far as I know. It's mostly aimed at companies who want to use the tech to launch their own coins and ICO's a lot cheaper and quicker. Obviously the whole China situation made things worse but in the long haul I can see both MNE and ART do really well
