Bitcoin mining is in short the hash-rate race between power-hungry computers. These machines require a lot of electric power to continue solving/computing complex mathematical puzzles. These cryptographic puzzles are created using memory intensive algorithm called the Proof-of-Work (PoW). Miners validate transactions and add the next block on blockchain, thus keeping the system secure and running. As a reward the miners collect $1000-$3000 in transaction fees from all validated transactions inside a block and also wins 12.5 BTC for mining the block. 2.24 2.23 2.22 2.21 2.20 2.19 2.18 2.17 2.16 2.15 2.14 2.13 2.12 2.11 2.10 2.9 2.8 2.3 2.4 2.5 2.6 2.7 2.2 2.1 2.0 1.0 Due to increased competition, the difficulty of mining has increased to such an extent that now you require specialized hardware to achieve enough hash rate to at least participate in the system. In 2009, 100 bitcoins could easily be mined within a day using CPU cycles of a simple home PC, but then as mining diffi
