去中心化的交易所，仔细了解过才知道，实质是用伪去中心化实现了高并发。
这样虽然不能称之为纯粹的去中心化产品，但他解决了目前效率和高并发应用这2个传统区块链最头疼的问题。
BTS的问题：
在比特股内，BTS作为其通用货币，被系统视为资产，任何人都可以质押BTS来获取对标物，如:bitCNY,bitUSD,bitJPY这类代币，再由承兑商进行法币间的交换。
整个设计里，只有一点不合理：因为BTS本身没有质押物，所以导致他没有价值背书，再用他去抵押出来的货币，自然也是没有任何价值背书，这就好像美国的次贷危机。
基于低价值或无价值的东西，再发行债券，或其他金融衍生品，当根基动摇了（类似前几天的数字币价格集体暴跌），必然会导致波及所有抵押物被强制平仓。
个人实在想不到如何解决这个问题。
如果让BTS以持有BTC,ETH,LTC等多个货币作为BTS基础，也同样存在数字货币集体暴跌带来的被动强制平仓风险。
如果让BTS持有现实资产（如黄金，房产，股票，债券），就更搞笑了。

To the center of the exchange, a careful understanding of it, in fact, is pseudo-decentralized to achieve high concurrency.
Although this can not be called a purely decentralized product, he solved the most troublesome issue of the current two traditional blockchain chains, which are efficiency and high concurrency.
BTS problem:
In the bit shares, BTS as its common currency, the system as an asset, anyone can pledge BTS to get the target object, such as: bitCNY, bitUSD, bitJPY these tokens, and then by the acceptor exchange of legal tender .
The entire design, only a little unreasonable: because the BTS itself does not have a pledge, so he did not endorse the value, and then use his mortgage out of the currency, of course, there is no value endorsement, which is like the United States subprime mortgage crisis.
When the fundamentals are shaken (similar to the collective collapse of digital currency prices a few days ago) based on low or no value stocks, redistribution of bonds or other financial derivatives, this will inevitably lead to the forced liquidation of all the collateral involved.
Individuals really can not think of how to solve this problem.
If you let BTS to hold BTC, ETH, LTC and other currencies as the basis for the BTS, but also the existence of digital currency collective crash caused by passive forced liquidation risk.
If you let BTS hold real assets (such as gold, real estate, stocks, bonds), even more funny.
