I only have an epic Water Tower so far and I won't sell it. Better to keep it and keep the costs low. I am looking at the rare ones and try to buy some for under 20 or 25 WAX for crafting my own epic silo cheaper and I believe both will rise and the epic ones get lower. But hard to predict because if the player base grow with New Waxchester both will rise because imo there is a lot of supply from the previous pump in November.
