Learn what bitcoin miners actually do, why the power bill decides everything, what a halving is, and why miners and AI data centers want the same Wyoming land. Four short rides. No wallet, no coin, no jargon.
Bitcoin mining is a race. Computers all over the world compete to add the next block of transactions to bitcoin's shared record. The winner gets newly created bitcoin plus fees. Winning takes enormous numbers of guesses, and guesses take electricity. So in the end, mining is a business of buying power cheaply and turning it into a chance at a reward. That is why miners hunt for cheap, steady power, and why places like Wyoming keep coming up.
Bitcoin mining is how new transactions get added to bitcoin's shared record, called the blockchain. Computers called miners compete to add the next block. The winner receives newly created bitcoin plus the fees in that block. Mining is also how new bitcoin enters circulation.
Miners gather waiting transactions into a block, then make huge numbers of guesses to find a value that gives the block a hash below a target. The first miner to find one broadcasts the block, and every other computer on the network can check it in an instant. This is called proof of work. A new block is found about every 10 minutes on average.
The halving is a built-in rule that cuts the block reward in half every 210,000 blocks, which works out to about every four years. The most recent halving, in April 2024, cut the reward from 6.25 to 3.125 bitcoin per block. The next one is expected around 2028. Halvings slow the creation of new bitcoin toward a cap of 21 million.
The guessing is meant to be costly. That cost is what makes it expensive to cheat the network. When more miners join, the difficulty rises so blocks still come about every 10 minutes, and total power use climbs. Estimates of bitcoin's total electricity use vary widely, but many put it in the range of a mid-sized country.
For most people in the US it is hard to make money mining at home. Retail electricity usually costs much more than the rates large mining sites negotiate, and machines are loud, hot and expensive. Profit depends on power price, machine efficiency, bitcoin's price and network difficulty, which all change. This page is education only, not financial advice.
Miners look for cheap, steady power, cool weather that helps with cooling, open land, and clear rules. Wyoming offers a mix of all four, and the state has passed a series of laws that recognize digital assets since 2018. Power costs still vary a lot by site and contract, so not every Wyoming location is cheap.
Hashrate is how many guesses per second a miner, or the whole network, can make. Difficulty is how hard it is to find a winning guess. Bitcoin adjusts difficulty every 2,016 blocks, about every two weeks, so blocks keep arriving about every 10 minutes no matter how much hashrate joins or leaves.
Both need a lot of cheap power, cooling and land. A bitcoin miner can shut off within minutes when the grid is stressed and can run at remote sites with a basic internet link. An AI data center usually needs power around the clock, backup systems and fast fiber connections, because customers expect instant service. Some former mining sites have been converted to host AI computing.
Yes, it is free, and no, you do not need a wallet, an account or any cryptocurrency. It runs in your web browser on a phone or computer and takes about five minutes. All dollar amounts and power prices in the game are simple examples, not live prices. It is education only, not financial or investment advice.
