I am a software developer based in Cambridge, UK. I develop several tools that help enhance the steem community especially the CN. I maintain a Steem Witness Node that supports the growth of the steem blockchain.

I am a Utopian Moderator. I review submissions in the development category.

I am currently the 8-th most delegated account - currently 303 delegators! on the STEEM Blockchain.

Delegation

Hive account@justyy is the 8-th most delegated (303 Delegators) project on steem blockchain (See below).

Delegation Rewards

In last 7 days, 116 SP were given out to the 303 delegators. Thank you!

The steem price is low and hence more delegations to Hive account@justyy as his delegation return APR% still stays the same.

Revenue and Expenses

1. Monthly SteemSQL cost: 20 SBD roughly 60 STEEM at current price.
2. Monthly Costs for Two Witness Nodes: around 100 USD
3. Monthly API server costs: around 150 USD
4. Monthly Domain Costs: 5 USD
   And not to mention time and efforts spent on: developing new tools, monitoring and upgrading the witness servers. It is profitable only (especially under such low STEEM price) if you are at Top 50, so please do support me by voting me as a witness or set as a witness proxy. Thanks.

I like STEEM and I do believe the STEEM - that is why I have been spending money and efforts on being a witness and promoting STEEM community via developing tools/applications, providing APIs, helping Utopian moderating work etc.

Delegate to Hive account@justyy

Hive account@justyy runs a automatic delegation service for a long time. Delegate to Hive account@justyy for at least 5 SP and start receiving daily payout as interests (from 8% to 10% APR). Also, as a supporter, the delegators will start to receive complimentary/curation upvotes (as a thank you) per day from e.g Hive account@justyy and a few other curation trails. For more information, read this. The voting weight algorithm is open source.

• Delegate to Hive account@justyy - at least 5 SP to join (automatically)
• Undelegate to @justyy (Quit) - SP returned by steem blockchain in 5 days
• View Current Delegators/Supporters

303 Delegators! Thank you!

Hive account@justyy is the 8-th delegated project on steem blockchain

Please note that the SP you enter is the final amount to delegate. For example, if you already delegate 10 SP and you want to delegate another 5 SP, you will need to enter 15 SP (instead of 5 SP) in the delegation form.
