How many Bitcoins can be mined? The Bitcoin protocol stipulates that there will never be more than 21.000.000 Bitcoins. This means that the Bitcoin supply is finite and the complete supply is fixed, potentially adding to its value as a result of scarcity. When all Bitcoins have been mined, the miners will no longer be rewarded with newly minted units but with a fraction of the transaction costs paid by others using the network.
What are mining pools? To improve their chances of earning a block reward, some crypto miners might pool their resources into what is known as a mining pool, using their combined computational resources to mine for Bitcoin or other mined cryptocurrencies. Block rewards are paid out according to how much processing power someone contributed to the pool. So the more processing power, the higher the chances of earning rewards.
