To earn tokens in the Steem blockchain you must be an active contributor and participant. You can start by signing up for a free account on an exchange such as Binance or Huobi, downloading a wallet such as Atomic Wallet or Guarda, and then depositing either Steem or Steem Dollars (SBD). You can then use your deposited funds to power up your account which will give you voting power and generate Steem Power. Then you can use your voting power to upvote posts and earn rewards in the form of tokens. Additionally, you can curate content on the platform by creating interesting content, interacting with other users, and engaging in discussion. This can help you attract more followers and ultimately increase your rewards. Finally, you can also earn tokens through writing and publishing content on the Steem blockchain, trading Steem and SBD, and setting up masternodes.
