1. upvoting, resteeming bounty program will start in several days (maybe in next week).
2. posting, commenting and referral bounty program will start in July (we lowered the priority for this because we need to fix our ranking algorithm first before we get a lot more users)

ETH address is NOT required. You can optionally withdraw your tokens to your ETH wallets, but we will offer an off-chain wallet for every Steem user.
