# Weekly Witness Update 
As a witness, I feel it is useful to have a weekly report, which will be produced every weekend at the hashtag #witness-report

# Last Report
[@justyy's Weekly Witness Report - 14/April/2019](https://steemit.com/witness-category/@justyy/justyy-s-weekly-witness-report-14-april-2019)

# Witness Status
[My Witness Page](https://steemyy.com/witness-data/justyy)

## Block produced in last 7 days
71 (+3)  blocks produced in last 7 days and rewarded 158750 VESTS in total (approximately 78 (+3) Steem Power).

## Witness Summary

Backup Server is cancelled to save the cost in the current bear market and considering the current witness ranking position are dropping (supporters are powering down)

## Delegation
@justyy is the 8-th most delegated ([315 Delegators](https://steemyy.com/delegators/?id=justyy)) project on steem blockchain (See below).

## Delegation Rewards
In last 7 days, 128.4480 SP were given out to the [315 delegators](https://steemyy.com/delegators/?id=justyy). Thank you!

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

## Revenue and Expenses
1. Monthly SteemSQL  cost: **20 SBD** roughly 47 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](https://steemconnect.com/sign/account_witness_vote?approve=1&witness=justyy) or [set as a witness proxy](https://v2.steemconnect.com/sign/account-witness-proxy?proxy=justyy&approve=1). 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.

I am not giving up .. YET, and I will keep working hard to bring something unique to the community.

## Delegate to @justyy
@justyy runs a automatic delegation service for a long time. Delegate to @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 @justyy and a few other curation trails. For more information, [read this](https://github.com/DoctorLai/steemit-wechat-group). The voting weight algorithm is [open source](https://steemit.com/busy/@justyy/bank-of-china-implements-a-new-voting-algorithm).

## 315 Delegators! Thank you!
*@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.
