Dear all,
I need some help regarding bitcoin transaction data for a research project.
Especially I'm interested in transactions between people and exchange markets (doesn't matter which market).
Is there a way to identify markets within the transaction log?
I read a bit about green addresses, but I'm not sure, whether the markets always use their green addresses.
Are there markets which always use the same address?

The research is about speculation, e.g. I'm interested in the following things:
When people buy bitcoins? When people sell them?
What's the average profit till people get off? What's the average loss...
Do people change their behavior while the bubble gets bigger and bigger?
And so on...

Let me know, if you have an idea. Thanks a lot!
