You should have a base somewhere, you or will invest some money, or you will do something for some money, or you will join the bounty programs and do some tasks in order to get some tokens.
After you get a base (some money) then you should create accounts in the exchanges and start trading, it may sound strange but with a small amounts don't expect to become rich immediately.
But after a while you will notice that your wallet/total balance will start increasing or decreasing based on the performance and based on the market flow.
