1 BTC =111.32 USD   so 111.32 for 1 bitcoin. not bad, but thats 1/2 value as when it was $232.00   

what do you see on the pc when you figure out the hash and get bitcoins?

how do you know which site to use? any tips on choosing a site?
are all the programs (miners) the same?
the miner programs come from the sites themselves? not sure how this works...
