In order to earn free money fast using your occupied dragon habitats in dragon skies game, you have to collect from the dragons first
Go to time and date setting on your phone device
Just set the date and time an hour or more to have much time you need to collect all of the necessary coins
After collecting those coins then go back to the game and collect from all of the habitats.
Note that this amount of time may differ from the type of habitat and the maximum amount of coins that it holds.
Go to the habitat menu in the shop and tap on each individual habitat served for you.
As a simulation the wood habitat can hold up to 500 coins before being collected but the magic habitat can hold up to 6,000 coins before being collected from it.
