In order to mine 1 Bitcoin on a MacBook Pro, it would take approximately 12 months if the user was mining solo. If the user was part of a mining pool, it would take approximately 3 months.
The reason why there is such a big difference is because when mining solo, the user is competing with everyone else on the network who is also mining for Bitcoin. However, when part of a mining pool, the users are working together to find blocks and are then rewarded based on their share of work done.
The process of mining Bitcoin involves verifying transactions and then adding them to the public ledger, known as the blockchain. In order to be eligible to receive rewards for mining, users must dedicate computational power to solving complex mathematical problems. The first user to solve the problem gets to add the next block of transactions to the blockchain and receives a reward in Bitcoin. The reward currently stands at 12.
5 BTC per block, but will halve every 210,000 blocks (approximately every 4 years). This halving process ensures that there will only ever be 21 million Bitcoins in existence.
To give you an idea of how long it would take to mine 1 Bitcoin on a MacBook Pro, let’s assume that the machine has a 2.5 GHz Intel Core i7 processor with 16 GB of RAM and is running MacOS Sierra 10.12.4.
Based on these specs, we can estimate that the MacBook Pro would be able to mine at a rate of approximately 13 MH/s.
At current difficulty levels, it would take approximately 913 days (or 2 years and 5 months) to mine 1 BTC on a MacBook Pro if mining solo. However, if we assume that the user is part of a mining pool that finds one block every week, it would take approximately 48 weeks (or 9 months and 2 weeks) to mine 1 BTC.
In conclusion, it takes a significant amount of time to mine 1 Bitcoin regardless of whether you’re doing it solo or as part of a pool. However, by joining a pool you can increase your chances of finding a block and receiving a reward much sooner than if you were going it alone.
