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:
MCR (Maintenance collateral ratio) adjusted from 275% to 290%
The maximum supply is adjusted from 21,000,000 bitCNY to 20,000,000 bitCNY.

Current parameters:

ICR (Initial collateral ratio) 330%
MCR (Maintenance collateral ratio) 290%
MSSR (Maximum short-squeeze ratio) 190%
MCFR (Margin call fee rate) 7%
FSO (Force settlement price offset) 2%
FSFP (Force settlement fee percent) 1%

The median feed price is 0.22 CNY/BTS.

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 0.12 CNY, the collateral ratio (CR) of the debt position with the lowest CR in the BitShares DEX is 150%, the corresponding black swan price is 0.08 CNY.

* the ICR value 330% for feed price 0.22 effectively means 180% for market price 0.12, and the corresponding black swan price is 0.0667:
0.22 / 330% = 0.120 / 180% = 0.0667

* the MCR value 290% for feed price 0.22 effectively means 158.2% for market price 0.12, and the corresponding black swan price is 0.076:
0.22 / 290% = 0.12 / 158.2% = 0.076

* the MSSR value 190% for feed price 0.22 means collateral of low-CR debt positions will be listed for sale at 0.22 / 190% = 0.1158 bitCNY
** the MCFR value 7% means the price for buyers' is 0.22 / (190%-7%) = 0.120218579 bitCNY
** 0.1158 / 0.12 = 96.5% which means the actual penalty for being margin called is 3.5%

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:
维持抵押率(爆仓线) MCR 从 275% 调整为 290%
债务上限 从 2100 万 bitCNY 调整为 2000 万 bitCNY

目前参数:
初始抵押率(抵押线) ICR 330%
维持抵押率(爆仓线) MCR 290%
最大轧空率(爆仓惩罚上限) MSSR 190%
爆仓费 MCFR 7%
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 2000 万 bitCNY

注:
按目前外盘价0.12算,内盘抵押率最低的债仓的抵押率为 150% ,黑天鹅价为 0.08 (注:该数据会根据债仓数据变化而变化)

330%的ICR结合0.22喂价,相当于价格0.12时要求180%的初始抵押率。
计算方法: 0.22 / 330% = 0.12 / 180% = 黑天鹅价 0.0667

290%的MCR结合0.22喂价,相当于价格0.12时要求158.2%的最低抵押率。
计算方法: 0.22 / 290% = 0.12 / 158.2% = 黑天鹅价 0.076

190%的MSSR结合0.22喂价,相当于抵押品最低卖出价为 0.22 / 190% = 0.1158
再结合 7% 的MCFR,相当于要吃爆仓单,最低买单价为 0.22 / (190%-7%) = 0.120218579
同时,0.1158 / 0.12 = 96.5% ,相当于实际爆仓惩罚为 3.5%

另外,现在这种情况,外盘价格上涨的话,很多在边缘实际抵押率本来可以不被爆仓的被爆仓,这个损失与责任谁来承担呢?
说的好像解锁了就肯定会涨似的。解锁了,外盘砸一下,还不是照样爆一大批。

再说,原来爆仓线在 1.6 ,现在才刚调到 1.5 ,还有一段距离,还没有爆过本来不该爆的。

Effectively you are doing an ICO capped at 5 BTC per day if the price for each ticket won't change. The total fund to raise is 5*40 = 200 BTC.

Quote
As you can see in this block https://bts.ai/block/53159405 bot-11 account “registered” 1 RUDEX.LOTTERY and got a transaction number TXID of d60c7ce9467043cf81acd5fdb1c5bc851d20faed.
If this value is divided by modulo 5 (number of combinations), then the remainder of the division will be the combination number of this ticket. You can verify the division remainder using, for example, the following service: https://defuse.ca/big-number-calculator.htm
In our case you need to insert the following line into the calculator 0xd60c7ce9467043cf81acd5fdb1c5bc851d20faed  % 5, which is equal to the value of 4, which is a combination for 30 GPH token win.
Just for the info:

It is very simple for a skilled programmer to "mine" (brute force) the TXID and only submit the transaction to the blockchain if 4 is the remainder, with no extra cost.

Guess how many times you need to try to get your desired value if the chance is 20% every time. It is 5 times on average.

IMHO the design is stupid.

Good luck anyway.

你的总体思路是:网关自己发展,理事会资金注资AMM池

以下是我的看法:

比特股内盘需要和网关共同发展,因为网关的发展是发展内盘用户的关键,直接影响系统的收入。

系统有一定的收入作稳定币的支撑,便可良好地发展稳定币,这样可以和内盘、网关互为正反馈。

如果单单关注稳定币,就像是比特股系统自己一个人在单干,系统是有收入,但不够。

没有壮大网关的发展,内盘的使用用户有限,只剩玩bitcny稳定币用户。

况且现在市场已经不缺稳定币,比特股的bitcny稳定币没有优势。

bitcny等稳定币经过长期锁喂价等事件,用户对内盘的稳定资产认可度已经大打折扣。

Quote
前提是:锚定资产市场不能有黑天鹅,不能有锁喂价/BAIP2这样的幺蛾子.

你说的前提会有吗?不确定性一直都会存在。

Quote
理事会大量大量大量大量注资一两个”锚定资产A/锚定资产B“AMM池

如果理事会可以注资AMM池,为什么不把这些资金用在开发改善,内盘开网关的基础设施上。

目前现运行的三个网关GDEX,RUDEX,XBTSX所拥有的资产,都加起来BTC总量只是50个左右。

也就是说内盘现在所承载的资产价值远远太少,加上bitcny等稳定币,就算全部投入到AMM池中,也都不及一个小交易所。

所以,AMM池短时间体量做起来很难,做起来的关键有赖于在网关引入大量BTC,ETH,EOS等其它资产

看看,“开发改善,内盘开网关的基础设施”和“BTC总量只是50个左右”这两件事,没有直接关系吧?
基础设施当然要做,但也要看准做什么,投入多少,产出的是什么,有没有市场,时间周期怎么样,等等。

“网关引入大量BTC,ETH,EOS等其它资产”,没错,网关开了几年,这些主流资产都有,但没多少交易,为什么?这不是基础设施的问题,是流量的问题。
主流币流量都在大交易所。但我们能分一点流量就饿不死。
开发新币网关,投入要多一点,但实际上交易所对新币竞争也厉害,网关能不能分到流量,还是看本事。

反过来说, AMM 池体量做起来是不难的,充钱就行了。
但最终还是要靠交易赚钱。

Quote
在我看来,说网关的发展是网关自己的事,相当于是说比特股我自己一个人单干就可以了。。。

换个思路,比特股是平台。

为什么要发展网关,因为比特股需要大量网关,来发展壮大内盘的用户,增加内盘所承载的资产价值。

54
我也希望是共同发展。
但一个巴掌拍不响。
再者熊市里做事确实难度大。

关于做市,我比较懒,不想跑机器人,所以更倾向于 AMM 池,但AMM池资金利用率确实也低。
说好不如做好,我个人已经注资以下几个池,总资金有近百万人民币了吧,不算多,但聊胜于无。
BTS/GDEX.BTC
BTS/GDEX.EOS
GDEX.EOS/GDEX.BTC

其实稳定币池很有潜力, ebit 开了个好头,但我个人手里没有稳定币,所以没参与。

理事会账上没多少钱,并且主要是BTS, 剩下的有点 bitCNY 已经投入到池里了。

AMM池 + 挂单做市机器人 + 搬砖机器人,串起来,差不多就有完整的交易生态了。
各人根据自己兴趣参与。
比如,ebit、我、理事会参与AMM,猴子、lebin、crazybot等做挂单做市,robin以及unemployed等做搬砖。
剩下的就是各自拓展交易深度和广度了。

更新了方案,如无意外2020年12月10日进行首期空投~
为你点个赞。
感谢你的付出。

其实对LP持有者进行LP锁仓领空投应该是最为合适的...感觉你这种空投方式被薅羊毛的几率太大了...
任何空投都会被薅羊毛。
还是创造收益+回购比较靠谱。

Quote
找一个多签的第三方账户是否可以利用"barter"功能进行迂回式的锁仓空投?!....


不知道现在BTS这种锁仓功能是否可以开发成通用模板,任何币种都可以按设定时间进行锁仓[email protected]
如果只是锁仓,用 vesting balance 功能就行了。配上 cliff 的效果更好。 你可以翻翻历史, 加密桥 CryptoBridge 当初是怎么玩的。

Quote

通用DAO治理模板功能开发着开发着也没下文了...

现在光一个主力开发实在是太单薄了,开工资拉人才是正途...
先确定做什么。
有事做才好开工资拉人,不然拉来都是薅羊毛的,也留不住。

这次 bitUSD 黑天鹅价是 0.0345 ,MCR 是 150%,也就是说喂价达到 0.05175 后即可复活。

为什么要继续保持Bitusd的MSSR是150%,而不是下调到正常水平1.01?


因为规则限制,全局清算后就不能调MSSR了。也可以说是BUG,修复需要硬分叉。
https://github.com/bitshares/bitshares-core/issues/2282

我主帖说的,基本上是基于现有情况,在不改代码的情况下可以如何操作。

bug可以修,代码需要改的可以改,但需要时间。
根本上说是排优先级、什么先做什么后做的问题。
