I've never bought gems before, and I've always just got them from mastering recipes or goals. I have a lot of coins though, and I just saw that you can trade coins for gems (2,400,000 coins for 100 gems, I think). Do you guys think it's worth it? Did the coin amount required for trade increase with the price hike?
The reason why I'm asking is because I'm no longer really interested in expanding (maybe because I'm annoyed at the price hike), and so if I trade in my coins, I can get gems and buy boxes and decorate my existing bakery with the gem-only items. I'm interested in hearing your thoughts!
