Purpose:
to restore the peg of bitCNY in the long run and mitigate the issue that some debt positions' collateral ratio is too low.

Changes:
ICR (Initial collateral ratio) adjusted from 330% to 180%
MCR (Maintenance collateral ratio) adjusted from 290% to 160%
MSSR (Maximum short-squeeze ratio) adjusted from 190% to 105%
MCFR (Margin call fee rate) adjusted from 7% to 3%
FSFP (Force settlement fee percent) adjusted from 1% to 3%
Price feed threshold adjusted from 0.22 CNY/BTS to 0.12 (temporary)
Price feed producers list: in.abit only (temporary)
Minimum feeds adjusted from 7 to 1 (temporary)

Current parameters:

ICR (Initial collateral ratio) 180%
MCR (Maintenance collateral ratio) 160%
MSSR (Maximum short-squeeze ratio) 105%
MCFR (Margin call fee rate) 3%
FSFP (Force settlement fee percent) 3%
FSO (Force settlement price offset) 2%
Force settlement delay 24 hour
Maximum force settlement volume per hour 0.5%
Price feed threshold 0.12 CNY/BTS (temporary)
Price feed producers list: in.abit only (temporary)
Minimum feeds 1

Borrowing is enabled. The maximum supply is limited to 20,000,000 bitCNY.


Note:

* As of writing, market trading price of BTS on CEXs is around 0.123 CNY, the collateral ratio (CR) of the debt position with the lowest CR in the BitShares DEX is 161%, the corresponding black swan price is 0.076 CNY.


Here is a summary to in.abit's price feed script:

* update up to 12 times per hour, at random intervals; no update if price change is less than 0.1%
* main data source is Binance and Huobi, with low-weight adjustments from AEX, Bittrex and BitShares DEX
* black swan protection is enabled
* price threshold is 0.12

Risks related to price feeds (market participants please be aware):
* due to the low weight of direct CNY market, the final price need to be derived from BTC and USDT markets, so the price may be a bit off
* due to potential technical issues, update of price may be delayed for a short or long time

参数调整目的:争取恢复 bitCNY 锚定,缓解部分借款仓位抵押率过低的问题。

今日操作:
初始抵押率(抵押线) ICR 从 330% 调整为 180%
维持抵押率(爆仓线) MCR 从 290% 调整为 160%
最大轧空率(爆仓惩罚上限) MSSR 从 190% 调整为 105%
爆仓费率 MCFR 从 7% 调整为 3%
强清费率 FSFP 从 1% 调整为 3%
最低喂价 从 0.22 调整为 0.12 (暂行)
喂价人清单调整为 in.abit 单人喂价(暂行)
最少有效喂价人数从 7 调整为 1 (暂行)

目前参数:
初始抵押率(抵押线) ICR 180%
维持抵押率(爆仓线) MCR 160%
最大轧空率(爆仓惩罚上限) MSSR 105%
爆仓费率 MCFR 3%
强清费率 FSFP 3%
强清价格偏移(强清补偿) FSO 2%
强清延时 24小时
每小时最大强清比例 0.5%
最低喂价 0.12 (暂行)
喂价人清单 in.abit (暂行)
最少有效喂价人数 1 (暂行)

借款功能目前开放,债务上限 2000 万 bitCNY

注:
按目前外盘价0.123算,内盘抵押率最低的债仓的抵押率为 161% ,黑天鹅价为 0.076 (该数据会根据债仓数据变化而变化)

另附 in.abit 目前喂价算法如下:
* 每小时最多更新 12 次喂价,时间随机;如果价格变动低于0.1%则不更新
* 主数据源为 币安、火币,同时AEX、bittrex 和内盘有少量权重
* 黑天鹅保护开启
* 最低喂价 0.12

喂价相关风险提示(请市场参与者充分了解):
* 由于人民币交易对权重较低,主要通过BTC和USDT折算得出最终喂价,而BTC和USDT价格取自外部交易所,可能导致结果存在偏差
* 可能因为技术原因,导致喂价更新不及时,甚至中断一段时间
