I am soooo sick of people telling me that an exchange is not a bank... Of course not, a bank is secure and will pay me interest, etc... and serves a completely different purpose.
An Exchange is where I put the coins that I've mined and I spend time day trading but, you can't day trade in any quantity unless you have some coins in the exchange. I didn't have a huge amount in my account, but I did have enough to matter to me. It takes way too long to transfer coins back and forth so trading opportunities are gone by the time the coins are available.
We need to be able to trust an exchange to be there, be secure and execute orders correctly in a timely manner. That is the bare minimum I expect, and that doesn't even consider that this is an extremely limited (feature wise) site in comparison to almost any brokerage firm trading Equities or Forex. It just shows the amateur nature of this market in general.
