If you spend your coins in gambling you would probably not have anything to save, just do trading and save the profits you gain from there but don't gamble them all because that wont earn you anything in coming time.
Yeah cannot expect any good result from gambling as majority of times you will be on loosing end, either trade it and if you don't have knowledge then better to save it for future.
So that you will know how trading works after that learn some any strategy in buying and selling set a margin.. this is what other traders do..
