I'd like to know what the most efficient keys are for exchanging gems to gold. I read somewhere on this forum that Gold keys are the sweetspot, but I'm not sure what to pay for them. Most offers on the Market are at 250gems, but every request is below 190 gems. I'm not exactly sure what I should be paying for them, any help on this?
Also, I haven't tried it yet, but when you go to the chest room and have a chest available to open and the sign says to pay an amount of gems to open the chest, does this give you a key or does the chest open right away? I was thinking i could just buy a gold chest and keep buying keys from it.
thanks for your help,
