Do bitcoin miners actually make money Possible Duplicate:
  How can I compute mining profitability?  




Do bitcoin miners like the one depicted in the video below with 24 server clusters actually profit from bitcoins at the current prices? Are the bit coin exchange rates high enough to cover their costs of electricity and hardware? And is there enough liquidity in the market to actually unload them?

Or are all these miners hoarding them in hopes the idea will take off in the future?

Miners have about 26% profit at the moment, that's includes only cost of electricity vs bitcoins sell price.
