I cannot agree that they know what they are doing exactly, the behavior is extremely amateurish due to the nature of execution.  The policies being inconsistent is another highly amateur move as it shows lack of intellectual due diligence.

In banks and other institutions you are required to give ID documents before a pence drops in to any account, as I pointed out in their own policies they stated this as well however they contradict this by allowing deposits and in addition allowing the trading that occurred, therefore violating their own written policies.  Would this not qualify as suspicious so they now need to give me their ID documents?  So this is obviously not a professional move because it is either one way or the other, not in the middle unless you are running a scam.  Besides there is not a "huge amount of money" the fact still remains that it was only 9 deposits and 4 withdrawals.  Even looking at that amount you can immediately tell that I was focused on trading not withdrawing.  Considering you and others keep saying "large amounts" I do not know if you are ignoring the screenshots, work for them and are trying to justify their behavior or are incapable of viewing the screenshots and understanding what you see.

Compliance of this nature for convenience reminds me succinctly of this quote
Considering the core principles of all cryptocurrencies I would be doing myself a disservice as well as the community, I am not about to go against core principles of these financial instruments creator(s) that is disrespectful, disingenuous and patently wrong.
