为了促进健康抵押,现重新开启 bitEUR(欧元)和bitRUBLE(卢布) 强清功能。

每小时强清限额调整为总量的万分之一。

其他参数不变。

目前 bitEUR 共有近400万BTS的抵押仓, bitRUBLE 有200多万BTS的抵押仓。

不觉得爆仓的系统收费高得离谱了吗?
MakerDAO 收13%,我们收8%不算高。

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

Changes:
MCR has been increased from 185% to 195%
MSSR has been increased from 150% to 151%.
MCFR has been increased from 6% to 8%.

Current parameters:

ICR (Initial collateral ratio) 295%
MCR (Maintenance collateral ratio) 195%
MSSR (Maximum short-squeeze ratio) 151%
MCFR (Margin call fee rate) 8%
FSO (Force settlement price offset) 2%
FSFP (Force settlement fee percent) 1%

The median feed price is 0.22 CNY/BTS.

Borrowing has been enabled earlier. The maximum supply is limited to 28,000,000 bitCNY.


Note:

* As of writing, market trading price of BTS on CEXs is around 0.13 CNY, the collateral ratio (CR) of the debt position with the lowest CR in the BitShares DEX is 109%, the corresponding black swan price is 0.119 CNY.

* the ICR value 295% for feed price 0.22 effectively means 174% for market price 0.13, and the corresponding black swan price is 0.075.

* the MCR value 195% for feed price 0.22 effectively means 115% for market price 0.13, and the corresponding black swan price is 0.113.

* the MSSR value 151% for feed price 0.22 means collateral of low-CR debt positions will be listed for sale at 0.22 / 151% = 0.1457 bitCNY
** the MCFR value 8% means the price for buyers' is 0.22 / (151%-8%) = 0.15385 bitCNY

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:
MCR 从 185% 上调至 195%
MSSR 从 150% 上调至 151%
MCFR 从 6% 上调至 8%

目前参数:
初始抵押率(抵押线) ICR 295%
维持抵押率(爆仓线) MCR 195%
最大轧空率(爆仓惩罚上限) MSSR 151%
爆仓费 MCFR 8%
强清价格偏移 2%
强清费率 1%
喂价 0.22 暂时保持不变

借款功能目前开放,债务上限 2800万 bitCNY

注:
按目前外盘价0.13算,内盘抵押率最低的债仓的抵押率为 109% ,黑天鹅价为 0.119

295%的ICR结合0.22喂价,相当于价格0.13时要求174%的初始抵押率。
计算方法: 0.22 / 295% = 0.13 / 174% = 黑天鹅价 0.075

195%的MCR结合0.22喂价,相当于价格0.13时要求115%的最低抵押率。
计算方法: 0.22 / 195% = 0.13 / 115% = 黑天鹅价 0.113

151%的MSSR结合0.22喂价,相当于抵押品最低卖出价为 0.22 / 151% = 0.1457
再结合 8% 的MCFR,相当于要吃爆仓单,最低买单价为 0.22 / (151%-8%) = 0.15385

I use for any cryptocurrency "satoshi" as smallest unit.

I understand.

Not only you, but also many of us have contributed and invested a lot without getting much back.

However, the chain still needs more contributions and engagements to move forward. In this sense, I would prefer allocating more resources to the ones who are actively contributing, but give less weight on contributions in the past.

By the way, IMHO it's a waste of resources if everyone piles on providing the same services, especially when our resources are limited. The law of diminishing marginal utility applies. It is best for everyone to find a position that is not easily replaced by others.

我认为在抵押排名第一的实际抵押率下降到合适的抵押率之后,可以尝试解锁喂价,需要喂价人提前做好黑天鹅防护脚本以应对外部市场变化。

解锁前操作:
1.ICR与MCR保持不变,限制总量不变;
2.MSSR下调至1.01,MCFR下调至1%;
3.解锁喂价+黑天鹅保护

解锁后操作:
1.分别降低ICR与MCR;
2.解总量;
3.在爆仓单彻底消除后,调整MSSR到1.1,MCFR至9%;
有道理。

I can help out with the feeds.
Any update please? I've added you as a feed producer but you've never published feeds?
I am out of active witness rotation. Hard to plan and jump on anything if my witness gets voted in on random few days out of a year.
I voted for you after 5.0 launch because I wished that you could participate more in the ecosystem.

I removed votes from you a few days ago because I hadn't heard from you in a week since you replied here that you can help out.

BTW if I am correct, you are not running any service except a block producer for the blockchain at this moment. No API node, no seed node, no price feeds, no other contribution that I can see. If you start to participate more I would like to support you, otherwise I am sorry.

Anyway, thanks for your contributions in the past.

A new 1.0 bitasset has been created today:

In addition, most of issuer permissions have been forfeited on all the 1.0 bitassets. Details updated to OP.
