People won't help you for Evan tokens. Firstly, they don't even know its price. Secondary, they can't be sure Evan will be listed somewhere and its price won't be dumped
It's really just a matter of educating people about the benefits and purpose of Evans. Once they understand the difference between Roks and Evans then they will be interested in it.
Is it really any difference between Roks and Evans if you say you will give 1 Roks for 1 Evan?
