With a coin based on PoW, the miners ARE important. Without happy plethora of miners, 51% attack occurs. Without the right crypto, there's also threat of the market crash from ASICs.
Miners are also the people actively involved with the community, and buying/selling. What in the fuck are you smoking bro?

Yes, of course, in your sense miners are important for EXISTENZ of coins, but the REAL VALUE of coins depends only on "normal" users and investors.
See on doge-community, who were not miners, but they had an idea, enthusiasm. the same with bitcoin/litecoin, it will be accepted overall because of distribution in real world for people.
The basis of a successful coin is the ideology!
If only the miners buy/sell, it leads to fail of coin. Many coins die just because the miner-community do not understand the importance to bring the coin into the real life!
One thing we might be able to do is connect more with the reddit community, but how do you break that barrier to entry is the hardest part of the endeavor.
