What do you do with it, how do you get it?
Income:
I have very loyal neighbours with whom I exchange gold. Furthermore, I have 3-5 friends, that don't play the game, but almost every day give me 1 gold, which I'm very greatful for. Last source of income: when the Gilded dragon was on sale for 300, I figured it would be a wise investment. So, at this moment, I recieve almost 12 gold a day.
I only bought the Diamond dragon couple of months ago when it was on sale for 17 euro, and shortly before that, I bought almost 2000 gold (also on sale) for 42 euro. Still have 1400+ gold left.
Spending:
I bought the 300 gold Gilded dragon, and some dragons that are on sale for max 200 gold. They have to be limited, and good looking (I know, it's personal), and usefull in the arena. Furthermore I bought 3 Champion Grounds when they were on sale, and, when I was still on Android, an Palatial Plateau and a Grand Gardens. Also bought a 2nd and 3rd nest, they're very helpful with world events and summonings. I don't buy the special items on World events: I don't think it's worth the money.
I almost never spend gold on speeding: if you have time to play, there's no reason to speed. Nor on Boosted breeding: don't feel like it's worth the money.
Most of my gold I spend on using ulti's in the arena.
Future spendings:
I'd like to have the fully upgraded Stables and perhaps the Diamond Temple, altho I have so many Diamonds (Mercury, Crusader, Diamond, Quetzal, Infinity, Gold) that it's almost not worth it.
Why this long post?
I was curious how others recieve and spend gold, so please, let me know your story
