Cryptocurrencies operate on decentralized peer-to-peer networks, allowing them to function without a middleman. Mining is essential for verifying transactions and creating new blocks in the blockchain. Crypto miners complete cryptographic tasks to prevent rogue nodes from adding erroneous blocks and can generate passive revenue if they can afford the required technology. There are five ways to mine Bitcoin, starting with CPU mining, which has become less profitable due to increased hash rates. GPU mining was introduced to boost CPU processing power but soon became obsolete. FPGA mining emerged as a more energy-efficient alternative to GPU mining, providing a return on investment within two years. Miners then migrated to ASIC mining, which completes proof-of-work calculations at faster speeds. However, ASIC-capable devices have a minimum threshold cost of around $12k. Cloud mining allows miners to rent ASIC machines, reducing upfront costs and providing easier exit options during bear markets. The crypto mining landscape has changed, but it remains relevant, and hiring ASIC machines from cloud providers is a popular option today.
