In the current climate, it takes a significant investment in equipment, cooling, and storage to make a profit from Bitcoin mining. It's not feasible to mine Bitcoin with a PC or GPU in the home environment. You can use a Bitcoin mining calculator to determine your profitability. Even if you purchase the most advanced miner available, you're still at a disadvantage compared to professional Bitcoin mining farms. For reference, if Google were to use all of its servers solely for Bitcoin mining (and abandon all other operations), it would only represent a tiny fraction (less than 0.001%) of the total mining power currently held by the Bitcoin network.
If you guess correctly, you'll earn Bitcoins and write the “next page of Bitcoin transactions” on the blockchain. Of course, miners with more computing power will be more successful more often, but due to the law of probability, it's highly unlikely that the same miner will always be successful. Once all Bitcoins have been mined, it is assumed that mining fees will continue to incentivize Bitcoin mining activity. The combined efforts of all miners in the group will make it more likely that the group will solve the original problem and receive the Bitcoin reward and transaction fees. The first miner to guess the number updates the transaction ledger and also receives a reward of newly minted Bitcoins (currently 6.25 Bitcoins).
Bitcoin mining has potential to be profitable, plus there is the fact that, as a home miner, you are contributing to the decentralization and security of the Bitcoin network. As mentioned above, the difficulty rate associated with Bitcoin mining is variable and changes approximately every two weeks in order to maintain a steady production of verified blocks for the blockchain (and consequently, Bitcoins released into circulation).The compilation of this block marks their moment of glory as they have now become temporary Bitcoin bankers who can update the Bitcoin transaction book. As Bitcoin becomes more popular and the mining reward decreases, Bitcoin mining fees will become more profitable. By entering all these numbers into a Bitcoin mining calculator, I get an answer that it will take me 3 years until I manage to mine 1 Bitcoin.
Some savvy crypto miners also run their miners more or only during winter months as these mining configurations can generate considerable heat. Last week, it extended its services to retail customers by launching a home mining program to sell Bitcoin mining equipment directly to customers so they can mine Bitcoin at home without having to pay extra fees for hosting facilities. As for heat, some Bitcoin miners have been able to take advantage of that excess energy, particularly in colder climates.
