Well in many alt coin threads I see people asked "what dev is doing", "how dev will promote the coin".
To be honest, I saw a few coin's dev promoted desperately their coins, but most of the promises go nowhere, it just creates some fancy imaginations for people to try to pump up the coin, the results? those who believed them suffered and lost.
For me, all alt coins I mined, I dump them whenever possible, and I keep only BTC. It is just a dream for people that one day an alt coin will become BTC-2nd. There's no such thing. Those who play with alt coins are traders, yes they do make profits, but that's a tough job and I can't do it.
Why I am mining alt coins then? The answer is very simple: it is much more profitable than mining directly BTC. Mining new alt coins are especially profitable - if they go to an exchange, most will, as exchanges make money from the commissions. As long as there are requests to do trades, they will list it. They listed things like Junkcoin and Sexcoin, I don't see what they can not list.
So no need to ask silly questions like "how dev will promote", it shouldn't matter.
ZEU is a great coin, because it is very stable and problem-free. I've been mining it from the beginning, and many others like GDC, ASC, FST, GLD, LK7 etc, so far my mining of alt coins are great.
