I have received assistance for the information below from a third party who does not wish to be publicly identified.

We were able to access to the raw transactions which are available in raw format in Archive. With these information, we were able to discover 6 new ZEC privvate wallets:



Results (STEP 3)

As of 2017-05-30, this cryptocurrency was being exchanged, based on the rate used by the ShapeShift exchange, at ~$2,243 / 1 BTC.

In May 2017, during these operations, the ZEC had, on the ShapeShift exchange, a value of ~$181 / 1 ZEC. That is, if we add all the transactions above, an amount of ~113,05739292 ZEC or using the transfer rate mentioned above ~$20,576.44551144.

This represents an exchange rate and expense loss for The Shadow Brokers of $2,685.

(23,261.70323364 - 20,576.44551144) = $2,685.2577222

In summary, The Shadow Brokers’ cash out graph would therefore be:
