What does mining bitcoins mean

Proof-of-Work
Cryptocurrencies like bitcoin, dogecoin, and litecoin are created through a process known as proof-of-work, in which miners around the world run high-powered computers that collectively validate transactions and simultaneously create new tokens. The process requires a lot of electricity, and because this is the only variable cost in a low-margin industry, miners tend to seek out the cheapest sources of power. How mine bitcoin “The profitability and ease of conducting cryptojacking at scale makes this type of attack low-hanging fruit,” said Matt Muir, security researcher for Cado Security, in a blog post explaining that cloud-based attacks are particularly lucrative. “This will likely continue for as long as users continue to expose services such as Docker and Redis to untrusted networks.”
How do you mine for bitcoin
One of the biggest drawbacks of Bitcoin is the vast amount of energy it uses to mine new coins, validate transactions and secure its network. At press time, Bitcoin's hash rate – the measure of all computational power dedicated to mining new coins – stands at 183 exahash (Eh/s.) This means bitcoin miners collectively attempt to crack the target hash of the next new block 183 quintillion times per second. Is Bitcoin Mining Profitable? A simpler cryptocurrency to mine is one that doesn’t call for the setting up of a large-scale crypto mining rig. While it was possible to mine bitcoin with laptops and PCs those days are over. The difficulty of mining, coupled with (ASICs) hardware for bitcoin mining, have killed bitcoin profits at home. How bitcoin mining works
Hardware 
Once the mining hardware is set up and the Bitcoin wallet is created, the miner must adopt strategies to install and configure the mining software. The miner has to apply technical knowledge to improve the mining capacity. The mining process then begins after the miner downloads a soft copy of the blockchain of Bitcoin and clicks on the start button. The miner needs to monitor the progress regularly to ensure that the mining application runs smoothly. However, the miner does not need to do anything manually and can rely on the mining hardware after the mining process is started. Because of the Bitcoin Mining process, new blocks are added to the blockchain. TRENDING Cryptojacking involves maliciously installed programs that are persistent or non-persistent. Non-persistent cryptojacking usually occurs only while a user is visiting a particular webpage or has an internet browser open. Persistent cryptojacking continues to occur even after a user has stopped visiting the source that originally caused their system to perform mining activity.
What is a crypto miner
Bitcoin mining is a highly competitive industry with narrow profit margins. The primary input is electricity, although significant upfront investments in hardware and facilities for housing the hardware are also required. The key hardware involved is known as the Application Specific Integrated Circuit (ASIC), which is a computing device specialized for running the Bitcoin hashing algorithm exclusively. Profitably relies mainly on consistent access to low-cost electricity applied to the most efficient ASIC hardware. Why is crypto mining so energy-intensive? According to minerstat, this mining setup would have earned us about 0.00177151 BTC within a 24-hour period. Meaning it would take us about 564.5 days (1 BTC/0.00177151 BTC) to mine 1 Bitcoin. That is roughly 18 months. In this calculation we have ignored the cost of the mining hardware, however, if you include it in the calculation, it might double the duration it takes to mine a single Bitcoin.
