I took to reading some reviews about SK and they all had the same thing in common. Every reviewer complained about the CE Market. This, mostly, being back when it was closer to 3K or 4K
I've also had difficulty myself trying to gather up 100 CE or 9000 CR to make an exchange when I only need a little of the other.
My proposal is simple.
Break up the 'package' of energy you must bid for down from 100 CE to 10 CE or even 1 CE.
Allow users to, using the market, trade smaller amounts of CE. This will allow people to more easily trade CE and thus not result in having to "grind forever" just to make a single trade.
