I interpreted the statement to mean 1 million hardware miners. It seems farfetched that they have 1 million customers hashing, and at least 500,000 (a majority) spent $500 ($250,000,000 total per month). I don't think GAW operates near the billions.
Maybe a majority of 100,000 users, ($25,000,000 per month) not 1,000,000 users.
Let's be honest, are any of the unverifiable claims made by GAW remotely believable?
$25 million is enough to buy ~2,500 GH/s (twice the size of the entire litecoin network). Don't forget that GAW already claimed to have hashrate equivalent to 97% of the litecoin network around a month ago.
So far all we know is they have a medium sized datacenter filled with Bitmain hardware and a few Zuesminers (not even close to 1000 GH/s).
To me it's obvious GAW is just using the "look, other people are giving us tons of money, so you should too!" tactic.
