Sorry, a couple of idiot newbie questions:

1. They claim in the FAQ that they don't buy or sell their own GHs, which is opposite of what I originally understood. So whose GHs are being traded? FalconFly has mentioned using his own GHs in their pool - is it just adding them to the pool or trading them as well?

2. Why the majority of transactions are so miniscule?

3. Why the prices in the orders are always in some weird fraction of a BTC, like 0.04002197 or something, not 0.04. How are those numbers generated?

4. How do I actually place an order - I thought I could click on a Sell order and buy it but it seems to bring up some random numbers into the Buy window. Should I manually type the long string of numbers into it? I've read https://www.cex.io/guide?start but I'm still confused - it's hard to even copy the numbers because the orders are constantly shifting in the window.

Thanks in advance,

prolom.
