bts.ai was born to fulfill the requirement for checking historic txid, and it works well up to now, however, bts.ai can do more to fulfill demand from BTS community, such as:

1. enable users to check activities in categories.

2. provide some features of trading statistics, for example, user can provide pair and time interval to see the buy/sell volume and average price in that time interval.

3. provide some charts to indicate the key figures of BTS, some can take cryptofresh.com/charts as a reference, some can be newly added, such as a charts to show the smartcoin balance and debt position data.

4. other necessary new features.

I hope more suggestions can come for upgrading, and bts.ai team can do some investigation and cost estimation of upgrading the explorer, and then create a worker proposal to get the needed fund to do the job. BTS community really need a prominent blockchain explorer.

as BTS price now grow up to above 2CNY, now it's time to adjust the rule to determine minimum collateral ratio in open market operation fund account.

we need the minimum ratio to increase with feed price, with a nonlinear decreasing rate。

I found below formula is likely a suitable choice, in the next price stage it will be used to determine the minimum collateral rate.



please advise if you have any ideas on this.

现在的爆仓机制有缺陷，但谈不上什么畸形。

BSIP30-38的一系列改动就在修复其中不合理的地方，包括“爆仓单按即时抵押率顺序成交”，“爆仓单可调高抵押率”，“允许只卖出部分抵押物”等等，这里面的一个核心思路是减少不必要的爆仓，说修改了更畸形那是瞎扯淡。

如果有人能准确判断趋势，那加杠杆操作挣钱是他的权利。而且，那种贴着1.75抵押的玩法同样有风险。并且，这种玩法并不是系统性风险的主要来源。系统性风险的主要来源依然是当大势由牛转熊时现在的爆仓规则太简单粗暴了。

靠个人的力量与大势作对当然是很可能死无葬身之地的，但是别忘了，公开市场操作是有源源不断的资金来源的。

而且，公开市场操作并不总是买BTS，需要的时候也会卖。

当前的BTS价格对BTC价格还有很大的关联，公开市场操作的目的之一是逐步减少这种关联，直到BTS价格基本与BTC价格无关。

谁要觉得可以蹂躏内盘就放马过来吧，前段时间那么糟糕的时候也没有黑天鹅，现在一系列的改进之后还怕了你了？

这么说吧，如果有人抵押倍数高，有人抵押倍数低，那么，那些抵押高的根本不会被清到，设置补偿比例多少都不影响。

所以，补偿比例，影响的实际上还是只有抵押率最低的那些单子。

那么，设置阶梯补偿有多少意义？不是说技术上不能做，而是做的必要性有多大。

理事会完全可以根据市场行情来调参数。抵押过热了，降补偿；抵押不够了，增加补偿。很灵活的。个人建议是先把这个参数用好，不够再加，前提是有充分理由。如果设置多个参数，最终还是要理事会来调；如果设置成固定参数，不可调，那如果有问题需要硬分叉升级解决，更麻烦。


另外，那些抵押倍数低的，加高杠杆的，本来就是为了利益最大化，同时也有风险。人人都想低买高卖，只是各人操作策略不同。这是自由市场，只要按照规则玩，就是合理的。

同意 btspad 的观点，bts/cny市场价就是对行情和各个参数的最明显反应，包括爆仓、强清补偿等等。
作为运营，理事会应该根据行情调节参数，但权衡利弊，可能有时候需要有偏向；这要靠有能力的人来做运营，当然最终还是要看投票。

我不太同意高抵押倍数的抵押单不会被强清的情况，去年10月份期间，高抵押倍数被强清的情况比比皆是，一度导致内盘几乎无人敢于抵押，直到巨蟹将强清补偿参数提议调至5%才有所缓解，而且这段时间长达一个月，理事会对强清补偿参数的调节及反应跟处理时间远远落后于市场反应，直到现在很多人还对调整补偿参数耿耿于怀，而且从强清开始形成到现在的运行结果来看，其起的作用并没有太大，很多时候起的是负作用，甚至有把抵押一清到底的恶果，而理事会在其中并没有起到太大作用，当然喂价机制在里面也起反作用。

采用强清补偿浮动参数，并非固定式的参数，其可以抵消理事会反应慢的问题，更能相当大程度跟进市场反馈，并能有效的保护高抵押倍数的抵押人，再者强清本身的一个目的就是为了抑制低抵押率，让大家保证高抵押率，浮动参数并没有不妥，而现有的由理事会调的固定强清参数在相当程度上是失败的，已经失去其本身存在的意义，很长时间已经失去其调节杠杆的作用，低了就恶意强清，高了就没人强清，根本没有一个合适的参数，哪怕巨蟹以前搞的TCNY其本身3%左右的参数也没有太大效果。

你可以加高杠杆，但是也要进行制衡，现有的规则是失衡的，并不利于抵押长期良性发展，既然有办法可以尝试，为什么还要固守老一套那？
而且有上下限参数可以调节，也可以加入浮动系数进行调节，并非是定死的数值，当然这些只是一些假设公式，可能有更好的线性公式。
再说，情况再坏，也没有比现在更坏了。

让强清补偿和抵押率相关如果可以实现，肯定是有意义的，IIRC，Maker就采用了这样的设计。
市场情况是在不断变化的，有事最低抵押率可能紧贴1.75，也有可能有时候最低抵押率会在2以上，区别对待是有意义的。
而且，补偿率一视同仁某种程度上也鼓励了低抵押率，因为低抵押率抵押效率高，而且有时候“晚爆不如早爆”的逻辑也很有市场。区别对待，是可以鼓励高抵押率的。

Hello everyone, We, GDEX team, now announce to apply for a witness - gdex-witness

In the past several months, GDEX has provided gateway service for coins like BTC, ETH, EOS, NEO, QTUM, GXS, BTM, BTO, HPB, ATN, etc. we tried to create more user friendly service for all BTSers, hope you can enjoy our service.

I, bitrab, committee member of Bitshares and Lead of GDEX team, have ran a witness by myself 1 year ago, finally I gave up as I am not professional enough on many technology things. now we have development team that include members focus on development/deployment/QA test/maintenance, I believe they can ensure the witness node to run well.

As a big shorter I understand deeply the importance of exact price feeding, in our view, fed price should reflect the market fact about with what a price people can convert BTS with one kind of fiat. we build our price feeding scripts based on this view.

Thanks for support!

up to now:

1.02M BTS from worker proposal filled to operator accounts.

in committee-cnytrader:
3.75M BTS in collateral, 840k bitCNY debt position, 191k bitCNY in buy orders. 1.07M bought with average price 0.846CNY/BTS. 2M BTS transferred in from committee-account accumulated BTS.

in committee-usdoperator:
0.42M BTS in collateral, 15k bitUSD debt position, 15k bitUSD in buy orders. 84k BTS bought with average price 0.127USD/BTS.

today is the first day that BTS from reserve pool are claimed and put into the operation plan, it's just a beginning, no significant effect to the market yet, however, while 200k BTS/day keep coming, the accumulated BTS in the operator accounts will show the power step by step.

with the coming hard fork to improve the margin call rule. BTS price will get great power to go up, let's keep on watching.
