This may be a stupid question but if every miner who uses claymore or visits this thread decided to form a price cartel - let´s say no selling under 100 dollars - wouldn´t that make the overall price go up only if we were actually able to sell it on that price? There would be still a lot of people selling it under priced, making people to only buy from them, while making the average exchange price still stay low. So what i´m trying to say here is that we would need to make the under priced zcash - sellers a minority, so they alone couldn´t supply the demand. Then the extra "leftover" demand either makes prices go up or the demand diminishes if the price is considered too high?

 While this is artificial, a real life use of zcash such as wide darknet adoption, online buying options or even a credit card adoption would make the prices go up naturally. Most of all Bitcoin (and therefore probably many other virtual currencies) are ruled to be VAT free in European Union: that might be a good stepping stone to make zcash purchases mainstream.

I´m an absolute noob when it comes to these issues so please do not judge me. i´m just throwing some points i´ve been thinking of. Feel free to correct me.
