I have entered this forum and seen loads of people excessively angry about having to wait for mist to regen. Instead of doing that, download the game team fortress 2, it is fun and free and just by playing you will find weapons and hats. each week you can find 1 refined metals worth of weapons and hats.
All you need to do is make a 1 off purchase of a 29p weapon from the store and then you can trade these refined metals for 325 Crystal energy.

1 trick is called idling - after starting up the game and becoming a premium account(29p) just search for an "idle" server. leave the computer on overnight and voila 325CE s worth or weapons and hats waiting for you

Another bonus of this is that there is no complex energy system so you can play and trade in that game for as long as you would like and make alot of profit like maybe Using a key (approx 750CE) on a crate (free) you could unbox an unusual hat worth $200 ( 700,000CE i beleve)
so stop complaining and get out there
