Right now the MHs held by users is only worth 165 BTC since the price of MHS is currently at .00033 BTC / MHS.
Can I ask where did you get this data from?
How do you know how many total MHS there are in the ledger, both for sale and in individual accounts not for sale?
He's just multiplying 500 GH/s by the current price. Because admin would never lie and would never sell more fake MHS.
