What a bunch of bollocks from OP. It's clear he is trying to spread fud to promote his own coin. He probably fears Quark since it's a contender and is growing rapidly.
That's why he is desperately trying to bash it.
First of all, your doubts are pretty much debunked in this thread. Here someone has similar questions like you without being an ass.
http://www.reddit.com/r/QuarkCoin/comments/1wupg6/those_of_you_who_mine_quarkcoin_why/Second QRK is designed to give less emphasis on mining incentive due to its rat-race of over emphasis on mining (Bitcoin's mining arm-race) which is not the only main reason that a currency exist. Also it makes the constant dumping by miners less effective because of it's model.
Mining has become controversial and sensitive issue due to rat-race of rich miners (ASIC rigs cost 10-15K), environmental hazards, PnD scheme etc. Mining is just an aspect of coin's feature not a zero-sum game. That's why Doge is desperately trying to change their algorithm to scrypt-jane because of their fear for asics, guess what Quark already thought about that and didn't just blindly copy and past LTC to regret it after.
Quarks distribution model is genius, because it needs a low daily maintenance cost to keep it's current price. Even if it would hit $1 now, it would only need $11,000 to maintain it's price, even less when the block reward halves. Again this is made possible by it's well thought economic model, where doge does horribly since it needs over $1million to maintain it's price, that's why it crashed from 230 to 130 causing many naif investors to get burned, because of it's flaws. They cared more about tricking people into believing that they have many coins which is causing problems right now.
Doge is just Feathercoin 2.0 with tight spreads and big sell walls, making it very hard to bypass. Without a meme it would have been faded into obscurity. Quarks infrastructure and community is only growing. Get your flaming elsewhere shibe.
Dude you may be a senior member with lots of experience, but I think you're too invested in a coin that could never really make it. I think the Quark rocket to the moon did take off but like the 1986 shuttle disaster Quark's o-ring failure has either happened or about to happen, in my view it's an accident rooted in history. Look below and tell me where Quark stands on the map?
