Mining hardware is specialized computers, created solely for the purpose of mining bitcoins. The more powerful your hardware is–and the more energy efficient–the more profitable it will be to mine bitcoins.
Yahoo Finances' Ines Ferre breaks down the numbers to know from Las Vegas Sands' Q3 earnings report.

This means you’re not only competing with every other solo miner on the planet, but you’re also competing with every pool, too. Even if you have more computing power than every single miner in every pool, do you have more than the entire pool combined? Probably (definitely) not!
While supply is limited, and the relatively high initial may be a deterrent, if you have access to cheap electricity you really can’t do much better than the S19 series.

my 3rd gen i5 laptop ran your python code at around 42 kH/s. Next i'll be trying to port it to perl. some basic questions that seem to be unaddressed beyond anything than vague generalities within the hype. I'm having a hard time grasping the "degrees of freedom" available to the miner. Clearly, the nonce comes first (32 bits) and the timestamp can be adjusted (but by how much?). Also there is some freedom in choosing which transactions to include (although it would seem you always want to include the most transactions possible so as to be the winner in case of a fork)? And finally, "the coinbase transaction can be modified". I *think* this refers to the "coinbase parameter" of the coinbase block, which in the case of the genesis block had the message "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks". That being the case, the coinbase parameter itself would seem to offer unlimited degrees of freedom. Hi Ken; I am not sure if this blog is still active but in the paragraph 'How Mining Works' you say 'In more detail, to mine a block, you first collect the new transactions into a block. Then you hash the block to form a 256-bit block hash value. If the hash starts with enough zeros[3], the block has been successfully mined' You didn't mention the nonce, also, I thought that in addition to the leading zeroes the hash has to be lower than the 'target hash'. If that's true, can you explain what the target hash is? Is it possible to reverse engineer and wind up with a valid nonce? wheezil: you seem to have a good grasp on the degrees of freedom, i.e. how much miners can change the block. Also note that the order of transactions gives you N factorial choices. As far as modifying the coinbase transaction, typically this is a combination of values from the mining pool (to ensure miners aren't doing the same mining) and "extranonce" values from the miner. Overall, there's enough degrees of freedom that mining isn't going to get "stuck". I am new to cryptocurrency. I have a doubt: when you implement these cryptocurrency algorithms (in python or some other programming languages), how do you tell machine to use GPU and not CPU in order to do math calculations? or it is always used GPU by default automatically and not need to explicitly tell it? In that case, how do you ensure that GPU is being used instead of CPU? Thanks to Mr josehp who help me become a millionaire by connecting my wallet to his mining stream i am so happy today i can get what i want i just got a new house,He make me earn 0.6 BTC daily, you can earn BTC also by email him and request for his help and he will also connect you to his stream right Away [email protected]

Most of the mining has been and still is located in China. In fact, as of 2020, it is believed that as much as 65% of Bitcoin mining occurs in China.
For a cryptocurrency like bitcoin, with over the roof block difficulty, it is a waste of time to mine with everyday computers. Miners with higher chances of earning profits have specially designed machines with high hashing power. These machines are ideal for mining activities entailing the solving of very complex problems. However, note that not all mineable crypto allows miners to utilize mining rigs. Some offer small scale miners a fair chance at partaking in the largesse available for the taking. Hence, an easy to mine cryptocurrency would allow you to connect your computer and start mining with little or no reason to worry about a lack of opportunities.
Another Chinese mining company, BIT.TOP, said it would no longer offer mining services for clients in mainland China.
Front Burner18:10Mysterious noise sparks discovery of crypto power plant in Alberta
Residents say the noise from a nearby bitcoin mining plant was ruining their sleep. The plant has since been ordered to shut down by the Alberta Utilities Commission, which said it is exploring penalties against the plant as it operated without approval. (Hailley Furkalo/CBC)
But explaining exactly what it is that these companies are doing all over Texas isn’t as simple. For many, it can seem mind-numbingly complex. To understand it, you need to know something about cryptocurrencies and blockchains and hexadecimals and something called “hash rate.” Amid all that complexity and the money to be made from it, I found a surprise when I visited Compute North’s multimillion-dollar Bitcoin-mining operation out in Big Spring this summer. The whole, massive, hot place is run by just two guys.
The WhatsMiner M30S++ again operates best between -5 and 35 degrees Celsius (23-95 Fahrenheit).
You should run some calculations and see if Bitcoin mining will actually be profitable for you.
Now that you know why they are operating and the advantages/disadvantages of cloud mining, it is time to make sure we pick the right contract. Here are some guidelines we would recommend you to follow when picking a provider.
ASICs take just a few steps to configure. Once you’ve configured your device and saved your settings, you’re ready to start mining and earning rewards. You are not locked into f2pool and can enter and exit the pool freely at any time. However, you will only earn mining rewards from f2pool while connected to an f2pool server.
