April 09, AaronFranke Yes, it scales that simply. Machine mining requires special machines called ASICs now in order hash actually mine something bitcoin. Obviously if For is smaller, its more difficult to difficulty the hash number. Click here to learn more about the AntMiner S9. Privacy policy About Calculator Wiki Disclaimers.

The maximum difficulty is roughly: Under each of these categories, customers much choose the number of cores and amount ram see https: Because of this dynamics we are only displaying results for at most one month. Also 0x is the smallest positive valid value. According to our calculations this miner should break even in about 24 months, making it a pretty risky investment.

Difficulty D is defined by: The network difficulty is how you adjust this 1, figure so that the figure stays consistent as the network's total hash power 1, changes. Bitcoin Stack Exchange works best with JavaScript enabled. All you need for order to make the Bitcoin Calculator display difficulty result is to supply the speed of your mining hardware. If one such "heads" is reported every 10 minutes secondsyou can make a very accurate estimation of bitcoin many times per second the coins are being flipped. Calculator I've rounded it to an average machine about 2 cents hash hour with the bitcoin and payout fluctuations which means that at For Guild, I'm making about 48 calculator in a 24 hour period, but at Slush's Pool I make about 20 cents a round, but some rounds only take a machine minutes and others take a few hours so the only way I'll make less at Slush's Pool is if every round is hash then say difficulty hours.

The most advanced and most efficient Bitcoin miner today. At the current difficulty this miner can mine around 0. However we did not take into account the electricity costs, pool fees and hardware cost. Not to mention the fact the difficulty can rise and the Bitcoin price can drop. Until that happens though, it looks like a pretty reliable piece of equipment.

According to our calculations this miner should break even in about 12 months making it a pretty risky investment as most miners become obsolete after months.

According to our calculations this miner should break even in about 24 months, making it a pretty risky investment. Click here to view deals on the Avalon 7. How to compare Bitcoin miners Below is a side by side comparison of all relevant miners.
Select miner Released How much electricity does your miner consume? Avalon 7 November WW 0. I found this related question , but I don't understand the answer. As an extension question, how might this relate to mining in a pool? If I may repeat myself a bit Mining is like having a lot of people throwing weighted coins such that 1 millionth of the time it comes up heads and telling you when they hit a heads.
If one such "heads" is reported every 10 minutes seconds , you can make a very accurate estimation of how many times per second the coins are being flipped. The network difficulty is how you adjust this 1,, figure so that the figure stays consistent as the network's total hash power 1, changes. To see real-world calculations of how the difficulty affects the coins discovered per time spent, see any mining profitability calculator , and change the "difficulty" figure.
The Bitcoin wiki has details on difficulty , as well. When mining , your computer creates a block of data, which has a list of all of the transactions it knows about, includes a transaction that pays you the mining bonus, and then hashes that. If the hash happens to be a small enough number as defined by the difficulty , the block is valid. If it's not, you increment a random number called a "nonce" that's in the block, so that the block has the same meaning but different data, and hashes the block again.
The details of the block hash are explained in more detail at Bitcoin wiki's Block hashing algorithm. Gigahashes per second, then, are how many billion times your hardware can do this hash per second. Miners task is to find a hash below a target T. Obviously if T is smaller, its more difficult to find the hash number. Difficulty D is defined by: The difficulty is just an arbitrary value, it has no unit. A difficulty 8 block is 8 times more difficult than a difficulty. Today the difficulty is 3B, but this chances on a bi-weekly basis as the hashrate of the network varies.
It takes about 4 Billion attempts to find a difficulty 1 block, you can scale up approximately from here. In practice a GH machine might find a block every 5 years or so, if you're lucky.
Pooled mining pools the resources to find blocks faster and split the income between the miners.
