There is also a 24h delay for settlements to prevents this exact exploit ..

Read the OP again... the attacker waits until just before the 24 hours are over before he starts manipulating the market price. So the delay doesn't help.

One way for shorters to protect their collateral is to show enough buy power (place buy orders) on external exchanges to keep the price high, and place enough sell orders in internal exchange above feed price to incentive buying instead of settling. Would it be profitable if make a bot to do this?

问题的根源在于bitcny应用场景太少，除了巨蟹几乎没有应用场景可以提供流动性

理想的锚定不是永远1：1，但也不是bicny：cny永远大于1，而是在1上下很小的范围内波动，但这需要内盘的bitcny和BTS交易对保持深度

我看目前不是锚定不锚定的问题，而是bitcny是否需要transwiser的问题

虽然目前对transwiser依赖性太强，但在初期阶段我们要学会变通，规则是死的，人是活的，规则可以改变

我选择在目前阶段支持巨蟹，但我不否定强制清算功能没有意义

本来之前一直宣传用bitcny来支付，2.0提高手续费后，基本上把支付功能堵死了。

不追求支付功能，走不出去，锚定就没有意义，只能在系统内自己跟自己玩，结果是死路一条。

完全靠UIA，和瑞波还有NXT有多少区别？
要知道，UIA的发行者是有动力将bts价格保持在低位的，这样他们的运作成本才会比较低。

抵押bts借出bitCNY肯定是为了使用。不用的话，去抵押干嘛呢？

以前还可以吃利息。

顺便吐槽几句。升级前那几天我正好搬家，没网络，搬家前忘记平仓，升级前也没法平，升完级利息没吃到不说，每个short单还要花40bts转账手续费+40bts平仓手续费来平仓，避免被强制清算。之前因为怕单子太大流动资金不够平仓，单子拆的金额小，数量多，结果升到2.0每平一单要花至少80BTS。。。亏死了。

Problem:
Mathematically, the value of the premium shorts sell to longs is a function of expected future variance in the value of that same premium - which makes it very difficult to calculate. However, markets do this all the time - it's basically pricing the derivative of a derivative. It's like trading options of VIX.
http://sixfigureinvesting.com/2010/01/trading-vix-options/

actually it is trading options with no expiration date on VIX...which makes the task...close to impossible.

otherwise great post + 1

No expiration?

7. Expiring In-the-Money VIX options give a cash payout.  The payout is determined by the difference between the strike price and the VRO quotation on the expiration day.  For example the payout would be $1.42 if the strike price of your call option was $15 and the VRO was $16.42.
8. The expiration or “print” amount when VIX options expire is given under the ^VRO symbol (Yahoo) or $VRO (Schwab).   This is the expiration value, not the opening cash VIX on the Wednesday morning of expiration.  VIX options expire at market open on expiration day, so they are not tradeable on that day.
9. VIX options do not expire on the same days as equity options. It is almost always on a Wednesday  See this post for upcoming expirations.  This odd timing is driven by the needs of a straightforward settlement process.  On the expiration Wednesday the only SPX options used in the VIX calculation are the ones that expire in exactly 30 days.  For more on this process see Calculating the VIX—the easy part.

In other words, there is a 3rd party who is benefitting from every trade and the existence of BitUSD: the BTS holder.   This is the party that is getting "something for nothing"... the BTS holder profits when people use the system. 

Many would say: why the value/price of a bts is still too low   

The BTS holder is the one who must finance the jump start because they are the ones who benefit once it is up and running.

They would say: I need to take out more money? No!

Rather than having the BTS holder fund all capital for the orders, it can "borrow" the capital required to place orders and gain leverage on its ability to kickstart a market.

Who borrow from who?

Just an idea, in order to encourage the using of bitAssets for payment:
1. Everyday (or every Saturday or so), start from an exact time, we offer that every account have the chance of transferring bitAssets N times for FREE (transfer fees will be fully refunded), with a pre-set total limit of T times, and maybe an amount limit with each transfer.
2. After that T times have been reached, we offer that the accounts which transferred bitAssets less than N times have the chance of transferring bitAssets X times at a fee discount of Y% (transfer fees will be partially refunded), with a pre-set total limit of Z times.
3. Maybe another (less) discount.

The budget needed for refund these fees comes from a worker position.

Does it make sense? The parameters need to be set after discussions.

(After seen lots of this kind of promotions in Chinese online-payment ecosystem)

Customers use BitUSD because it provides them the convenience and freedom of a cryptocurrency, and has the lowest transfer fees of any other payment platform.

The transfer fees are not as low now.
Are we coming back to advertise BitShares as a payment platform? Haven't we argued that BitShares is mainly in exchange business?
