bitfinex和campbx早就有隐藏挂单功能了。lakebtc这种不入流的小站，站内交易对比特币外部价格没有丝毫影响，噱头而已。如果huobi、bitstamp搞隐藏挂单，那就是个问题。不过隐藏挂单一般收费较高，限制了这类挂单的产生。

借這個機會我說說國外的交易所，campbx的交易量實在太低，就不說了。
bitfinex之前交易量穩步上升，甚至在一段日子超越老大bitstamp，令人感覺是妖魔當道...
首先，我在bitfinex是有交易的，bitstamp也有。bitstamp給人的感覺就是國外版的btcc，作風正規大氣。bitstamp的提幣有可能是要等好幾個小時，但是這個事實其實是反映了bitstamp的絕大部分的幣都在冷錢包，他們是把當時用戶存進的幣來滿足提幣。因此只要當時用戶存進的幣不足以滿足提幣，提幣的都要等用戶新存的幣直到滿足提幣量。因此，大家在交易所提幣都能立馬出現在blockchain都最好思量一下到底這個交易所的冷錢包到底是怎麼一回事。

Bitstamp雖然有一個非常煩人的KYC，這東西令很多人一怒離開bitstamp不回頭，大家可以在論壇的英文版找到很多類似帖子，但是瘦死的駱駝還是比馬大，現在bitstamp還是老大。真是要感謝天，讓我覺得相對正氣正能量的bitstamp可以穩坐老大的位置，不然真是妖魔當道了。

還有就是bitstamp的USD提現從來都是很regular的，說好多少工作天到就多少天到。反而，bitfinex就令人很費解。bitfinex有特快提現的服務，一個工作天內匯出收費1%，5個工作天匯出就是0.1%，我想基本上沒有什麼人會吃飽撐着要這個特快服務。這個服務很明顯就是針對搬磚的！當然你也可以選5個工作天內匯出。那麼好了，既然有人給1%選1個工作天匯出，那麼就要對得起給了1%的人，因此給0.1%基本都是第5個工作天匯出。如此所為，正常大氣的交易所所不為！

還有就是bitfinex說要準備美元應付提現，這是我和他們交互過程裡面得到的信息。我就很納悶，為何要準備呢？現金都拿去投資了？bitfinex提供P2P借貸，借貸雙方的現金都不能提現，那就是說絕對有充裕的資金可以長期做投資，導致客戶提現的現金的時候需要準備現金。這裡面道道值得大家思考。

上面東西只是個人隨筆，個人感覺+猜測。

campbx去年是国外第四大交易所，排在mtgox、bitstamp、btce之后，超过bitfinex，只是后来没落了。冷钱包一般存80%－90%的币，剩下存热钱包，这种量完全可以保证实时提币，mtgox、btce都是实时的。不实时提币的交易所，并不是防平台钱包被盗，而是防客户的账户被盗。

bitfinex提现还需准备，确实是个问题。私自动用平台内的客户存款去搞实体经济、放贷，是所有交易所都在干的活，不过起码得留一两成现金应付挤兑，如果连普通的法币提现都要准备，这风险就比较高了。

我把bitfinex官方對於usd提現發出來給你看看：
bitfinex不歡迎經常提現的人士！

Guys

a few replies to your questions:

1) Deposits - withdrawals fees: To put things into perspective a customer can now withdraw or deposit 30,000 usd and be charged a fee of 30 usd.
I frankly speaking don't believe this is even a problem to talk about in case you move money in and out once in a while.
Bitcoin is not a treasury bond yielding 3% a year, it is highly volatile and I believe we are making much ado for nothing.
Please understand our current financial system is based on checks and parameters.
The more we move in and out of our accounts, the more banks will be likely to notice our flows, the more attention we will get.
What we are trying to discourage here is not an occasional deposit or withdrawal, it's people moving money in and out daily as there was no tomorrow.
This behavior is putting our system under stress and is representing a potential threat to our security.

2) KYC-AML: Once again, we didn't suddenly get crazy or bought up by the Big Brother.
If you don't have a passport, you surely have a driving license, if you don't drive you can go to a public notary and have your identity verified on a piece of paper with your picture and your name and address written on it (auto declaration of identity).
For any exception I'm sure we will find a solution.

Due to the recent bankruptcy of MtGox we are facing increased attention by local authorities and regulators.
In the last days we went thru an audit performed by the Custom and Excise Department, which went well.
We always observed AML/KYC procedures, but we were kindly required to step up one notch due to the "particular nature" of Bitcoin.
I completely disagree upon the fact that Bitcoin or any other Cryptocurrency is the ideal mean for criminal actions (cash is a much safer mean for criminals) , but nevertheless we need to comply with the rules if we want our business to prosper and our customers' money to be safe.

Platforms are centralized entities and they can either decide to comply with rules or end up like Liberty Reserve.
Not much we can do about it, at least for the time being.

I hope that this helps
