How much money does it cost to solve a block of Bitcoin?

If someone were to spend a certain amount of money to rent or purchase hashing power to solve a block of bitcoin, how much would that person have to spend? Any thoughts?

Mining has reached equilibrium. If you invest a certain amount of money in mining gear it will produce about the same amount after some period of time depending how cheap electricity you can find. After that, your gear is outdated and it won't produce anything anymore. Only manufacturers can make profit because they have the fastest chips early and they won't sell those cheaper than they are expecting return.

Block reward is currently 25 BTC so it would cost approximately $10000 to have enough mining devices to solve one block before these devices probably won't solve anything anymore.

If your talking cloud mining the cost is the price of the hash power plus purchase fees plus maintenance fees. at home the cost is the price of the miner, shipping, supplies (a shelf, psu, network switch, network cables, fans, and surge protectors), and finally electricity. You may also have to use your ac in the summer; driving up the electric cost. surge protectors can plow out form the excessive; adding additional cost to mining.

If you are talking cloud mining cost can be very substantial. As an example I will be using a site like eobot. You could possibly get enough hash for about 420 BTC to get 1.3 bitcoin a day maybe. And you can see it would take 323 days just to get an ROI. but you shoudl have that hash for another 1497 days after your ROI. Thuis giving you a complete profit of
1946 BTC in a 5 year investment. ( these calculations did not incorporate difficulty rises or reward cuts)

If you are renting hardware for 24 hours to hit a block you will need a minimum of 4 PHS of power for 24 hours and hope to hit a block (which is not guaranteed) you would have to spend 60 BTC in order to try this so you would pray you hit 3 or 4 blocks (which COULD happen) in 24 hours to even make your money back. then if your renting hash you will need your own site and your own pool for personal use only. Renting hash and mining in a pool is absolutely NOT profitable in any way. Well maybe if triplemining would pay it out it would be worth it to rent all that hash and point it to triple mining, But i wonder if someone actually did that if they would even be able to pay that member what they really earned. Other than that you would need to have your own site and pool to solomine for yourself.

If you are talking your own equipment again you will want 3+ PHS of power, a stand alone building set up with the correct heat exhaust and cold air intake dehumidifier and solar energy. with that much power consumption the solar power alone could cost in the hundreds of thousands not to mention the equipment purchases. if we use S4s we can get an s4 right now for about 1400 dollars shipped. thats 2 THS using 1300 watts of power you will need a minimum of 1500 machines to get 3 PHS. So start up you are looking well into the millions of dollars in startup costs with no or very little overhead once completed. If you do this plan you will have no electric costs and 3 PHS of power that could actually bring in over 50 BTC a day with enough luck right now.

For just 1 BTC a day average you may want a minimum of 500 Thash and solar to power them and if your lucky you will solve enough blocks in a month to equal 1 BTC or more a day average.

HOWEVER you were so very broad in your question to honestly answer this question, you can buy 1 single 1 THSmachine for 500 bucks right now spend the 33 dollars a month to run the machine and "POSSIBLY" solve a block in 8 months so if this were the case you would have 764 dollars invested. and it would depend on the value of bitcoins at the time you solved the block as to how much you would make, if you solved the block and the rates were 370 like now your reward would be 9250 dollars for a profit of 8486 in 8 months. ( this is a very VERY best case scenario with lots of luck and would involve the capitol to pay for the equipment and its electric costs for the 8 months it runs.)

Nice analysis.

If you started now and expect the diff to rise as earlier then you have 5 % chance to find a block.
