The address Franktank has highlighted above also belongs to this exchange.
This suggests to me that this address was for the purpose of converting some coin to cash, 500 BTC at a time, in most cases. Coins coming from the exchange could potentially be from buyers of equipment who used the exchange as an intermediary to convert their cash to BTC to buy goods. This has a better chance of being true if there is a compelling reason for these purchases to frequently be in the 300 BTC range. The random variance in the BTC received from the exchange would suggest they were paying for something priced in currency.
That seems like a good analysis to me its possible that some of those coins are being converted to exchanges for Fiat and then used to purchase more gear or equipment for sales.
In that case the question is what the money is going towards but we probably won't know for a while
A few more days left in August for dividends to resume and its past Wednesday though so hope to see something in September.
