Exchanges and AML / reporting of large volume traders - Information

[Jonasch]

If you trade large volumes on an exchange, especially if it involves fiat currency trades, it would be good to know how this affects your privacy.
Most centralized exchanges have KYC in place so unless you submit fake documents, they know your ID and place of residence.

If you trade a high volume, what are the reporting requirements, what are the limits, who do they submit your details to and what details do they submit?

Which exchanges voluntarily submit information to tax authorities in your country of residence or to the country that issued your passport or to the banks they work with or to local authorities in their jurisdiction? 

How much do you have to trade for them to start asking you AML questions, or start asking you to sign AML statements? If you return such a form / statement to the exchange, who will they give it to?  The bank they work with for fiat transfers, or also to other authorities?


Please collect specific information in this thread, no wild speculation.

Who reports what and when?

Post only if you are fairly sure of your source, from personal experience or if you work for an exchange, bank or authority.
