What an eventful week it has been regarding cryptocurrency exchanges! We witnessed CZ stepping down, Bittrex announcing the suspension of its operations starting from December, and Kraken facing a significant lawsuit. There are a few key points to consider:

1) Is the recent decline in exchanges' fortunes a result of natural market forces or deliberate manipulation? This question might seem rhetorical given the circumstances.

2) With Bittrex shutting down, many users are left wondering where they will migrate their activities. Have you made any decisions regarding your future exchange of choice?

3) Could these exchange-related developments potentially trigger a major unforeseen event (a "Black Swan" event)? Or will the approval of a Bitcoin ETF override all other concerns and become the focal point of attention?
