title_body: What is the expected ROA (Return of ADA) after all coins are minted? After all coins are minted as far as I know the rewards will come from the transactions fees. At the moment we have 4.5 to 6.0% annual return of staked ADAs. When and how this will change after we reach 45 000 000 000 coins in circulation?
upvoted_answer: In ADA all coins are already minted. The total supply is 45 billion tokens. About 13 billion coins are not used and are &quot;locked&quot; in the treasury. It is used to be able to pay out the rewards for every block created by the stakepool and from where you will get delegators' awards. Because there not so many transactions to pay for, all the block awards the missing coins are used from the treasury. Once the transaction fees are sufficient to pay out all the block rewards, the treasury will only be used to fund proposals in what is now called Catalyst which in due time will start to solve the Voltaire stage. When Voltaire is ready it will be up to the community what to do with the rest of all ADA from Treasury.
  And this is a very interesting idea to vote the greedy out in favor of the Cardano Ecosystem to be sustainable.
