Nope. The interest rates will likely adjust, but not up the roof (what is considered the roof btw?  ).

How exactly?  To the people watching the logs, those insider trades would be indistinguishable from normal trades.

Without the insider trades, an outsider would occasionally see a difference in price lasting long enough for him to exploit.  With insider trades, there would be fewer such opportunities; and when one appears, before the client can execute his trade there would appear another trade exploiting the difference and eliminating it.

Specifically, for example: the outsider sees that on exchange A the highest bid is 450$, on exchange B the lowest ask is 440$. He submits a buy order on B for 440$, but before it gets executed, someone else buys that offer; his own order just lands on the book, unfilled, while the lowest ask on B has jumped to 455$.  How can he tell that the buy that succeeded was insider arbitrage, rather than a normal trade at B, or A-B arbitrage by a luckier competitor?

With no regulations and no auditing, exchanges could make lots of money besides the fees that they charge.

For instance, by delaying the trade logs for a couple of seconds, they can intercept client trades and "steal" some of their money.  Suppose that the lowest ask is 500$/BTC and the highest bid is 480$/BTC. Supose that Alice posts a sell offer of 1 BTC at 485. One second later Bob, who still cannot see Alice's offer, posts a bid for 1 BTC at 495.  Normally Bob's bid would be filled with Alice's offer, and he would save 10$.  But the exchange operator sees the two crossed orders, and inserts between them a buy order of 1 BTC at 485 (that takes Alice's coin), and a sell offer of 1 BTC at 495 (that fills Bob's bid).  The two transactions show up in the log and everything seems normal, and both Alice and Bob are happy that their orders got filled so promptly -- but the 10$ now goes to the exchange, instead of Bob.

Similarly, if two exchanges agree to show their order books to each other, a couple of seconds before they are posted to the public, they can exploit all opportunities for arbitrage between them.  Any client who tries to do arbitrage will then find that the prices have always shifted against him between the time that he places an order and the time that it gets executed.

There must be many other tricks, even more profitable than these, that exchange operators can pull.  I suppose that zero-fee exchanges, like Huobi and OKCoin, get their revenue from such insider trading.  Iam told that such tricks are totally illegal for regulated stock and currency exchanges.

Obviously, any money that the exchanges make, from fees or otherwise, must come out of their clients' pockets.

China is the world's biggest exporter, and the world's second importer, with 1.2 billion people!
So yeah the growth in China's economy is huge.
By 2020 , China is expected to surpass the USA in gdp.  

Of course I don't trust exchanges. Look at bitcoin exchanges' histories, generally. Think about Gox. I spread my coins across 5 exchanges (3 BTC/USD, 2 BTC/alt), to keep from having my trading coins in one place. I know the floor could fall out at anytime.

Ding ding ding! People that once had solid middle class jobs with full benefits are now working shitty independent contractor jobs. It's not really the same thing.

There are many such ways to do this; have a good credit record, not default on loans, have high interest rates, have a strong legal system, have a good business environment, have high quality workers, good infrastructure, political stability, high exports, strong financial system, etc.
Now many of those are long term sort of things, but short term, interest rates, balance of trade changes, political stability, etc.

Money laundering will always exist.
It will probably get harder with time (in what refers to bitcoin), but there will always be a way.
Maybe a time will come where cash becomes the main vehicle for laundering

Large scale foreign purchases work as well -- very cheap (with bitcoin). But obviously, any company of scale could not operate in such manner, given that most overhead costs would need to be paid in fiat.

From a merchant standpoint, cash = no fees. From a consumer standpoint, some level of anonymity with purchases. And some business still take only cash, as ancient as it sounds. My favorite Thai restaurant is cash only.

I think the current price is very low to make a profitable mining, some people say it will reach the $1000 or more by the end of July, so we

need to wait. A good option for now would be ALTcoins mining.

Your logic doesn't make any sense, you agree the software is worth more stand-alone, but that same software tested and running live/doing trades/having around 500 free visits daily/getting around 20 users daily is somehow worth less? On the contrary the software stand-alone would actually be worth less, although not by much as I've priced this auction very competitively already.
Also, we did not just buy a "custom script" as you suggest, I thought it was clear we are engineers by trade who made everything from the ground up and completely tailored to cryptocurrencies.
I think it's fair to say you are not interested AcoinLLC, you seem someone who invests in small businesses expecting a steady, mostly passive return. Running a financial exchange is obviously not something for you, it's a very serious project to take on I really want to warn people for that, this is really not something that can be approached like you do small businesses. We can argue all day about what you think is a fair price but it's really rather pointless.
