# Coin Mining Hardware - The Facts

If you're mining Bitcoin, you do not need to calculate the entire value of the 64-digit number (the hash). I repeat: You do not need to calculate the entire value of a hash.

Remember that ELI5 analogy, where I wrote the number 19 on a piece of paper and put it in a sealed envelope

In Bitcoin mining terms, that metaphorical undisclosed number in the envelope is known as the objective hash.

What miners are doing with these tremendous computers and dozens of cooling fans is guessing at the hash. Miners make these guesses by randomly generating as many"nonces" as possible, as fast as possible. A nonce is short for"number only used once," and also the nonce is the key to generating these 64-bit hexadecimal numbers I keep talking about.

The primary miner whose nonce generates a hash which is less than or equal to the target hash is given credit for completing that obstruct, and is awarded the spoils of 12.5 BTC. .

In theory you could Attain the Exact Same goal by rolling a 16-sided die 64 days to Reach random numbers, but why on earth do you want to do this

As you see here, their contribution to the Bitcoin community is they confirmed 1768 transactions for this cube. If you really want to find all 1768 of these transactions for this block, go to this page and scroll down to the heading"Transactions." .

There's no minimum target, but there is a maximum target determined by the Bitcoin Protocol. No target can be greater than this number:

Here are some examples of randomized hashes and also the criteria for whether they will lead to success for the miner:

You would have to get have a peek here a speedy mining rig or, more realistically, join a mining pool--a bunch of miners that combine their computing power and divide the mined bitcoin. Mining pools are comparable to those Powerball clubs whose members purchase lottery tickets en masse and consent to discuss any winnings. A disproportionately large number of cubes are mined by pools rather than by individual miners. .

In other words, it is literally only a numbers game. You cannot imagine the pattern or make a prediction based on previous target hashes. The difficulty level of the most recent block at the time of writing is 2,874,674,234,416, i.e. the chance of any given nonce producing a hash beneath the target is just 1 in 2,874,674,234,416--less than 1 in 2 trillion. .

## The Ig Bonds Statements

The aforementioned website Cryptocompare offers a helpful calculator which permits you to plug in numbers such as your hash rate, power costs etc. to gauge the costs and benefits.

Mining rewards are paid to the miner who discovers a solution to the puzzle first, and the probability that a participant will be the one to find the solution is equivalent to the portion of the entire mining power on the network. Participants which have a small percentage of the read what he said mining capability stand a tiny chance of discovering the next block on their own. For instance, a mining card that one could buy for a couple thousand dollars would represent less than 0.001percent of the network's mining energy. With such a small chance at finding the next block, it might be a long time before that miner finds out a block, and the difficulty going up makes things even worse. The miner may never recoup their investment. The answer to this predicament is mining pools. Mining pools are operated by third parties and coordinate groups of miners. By working together in a swimming pool and sharing the payouts amongst participants, miners can find a steady flow of bitcoin starting the day that they trigger their miner. Statistics on a few of the mining pools can be seen on Blockchain.info. .

Sure. As discussed, the easiest way to acquire Bitcoin is to purchase it on an exchange such as Coinbase.com. Alternately, you can always leverage the"pickaxe strategy". This is based on the old saw that during the 1848 California gold rush, the wise investment was navigate here not to pan for gold, but instead to create the pickaxes taken for mining.

In a crypto context, the pickaxe equivalent are a company that manufactures equpiment used for Bitcoin mining. You can look into companies which make ASICs miners or GPU miners. .
