The difficulty in mining has gotten so high that small miners like myself have to shut down. Even at it's current price of .010739, b.mine still is a lot cheaper than cex.io and the dividend is consistent. In hindsight I should have invested the money I put into the miners into b.exch instead.
Yes, one of the continued benefits of B.MINE is that there are no maintenance costs - MINE itself may not be profitable in the long run (no one will know until all is said and done, of course), but there are no overhead costs to sap the mining payout (like PETA, CEX, etc, which are backed by actual hardware).
