You can exchange coins for different details and clothes items and use them for further upgrades. Crystals are used for buying and upgrading parts if there is not enough coins. You will also need crystals for buying special parts, attempts in challenges, checkpoints in Planets and additional spins or Lottery Tickets. You can use spins to win some coins and cool stuff on the roulette.
