The overall supply of crystals is beginning to shrink at a fairly rapid rate now because there are some members (myself included) that are really focusing on adding as many factories as they can.
For a while I was maxing out my factories but not moving on to the next property until I had also maxed out my REGEN crystals too. This actually feels like it cost me time and production value and now I'm trying to catch up on the factory build outs with the hopes that I am still able to put factories on all of my properties before they run out.
Right now I've created 323 factories, all of which are maxed out with 5x crystals which essentially means that I should be able to produce 323 new crystals every single day from my factory production but I do not know as of yet what will happen when the overall supply runs out. Will I still be able to produce more crystals even beyond that point, I'm really not sure at this point? Either way, I'm going to keep plugging along because these crystals are valuable for the Spark Quest layer 2 game.
