When it comes to Bitcoin mining, there are many different factors that will affect how much Bitcoin you can mine in a day. The most important factor is the hashrate of your mining rig, as this will determine how many hashes per second you are able to generate. The higher your hashrate, the more Bitcoin you will be able to mine. Another important factor is the difficulty of the Bitcoin network, as this will determine how many hashes are required to solve a block and earn a reward.

If the difficulty is high, then it will take more hashes to solve a block and earn a reward, and vice versa. Finally, the amount of time you spend mining will also affect your earnings. If you only mine for a few hours each day, then you will obviously earn less than if you were to mine for 24 hours each day.

Assuming you have a hashrate of 3090 TH/s and you are mining on the Bitcoin network with a difficulty of 18.5 billion, you would be able to mine approximately 0.0016 BTC per hour, or 0.0384 BTC per day.

This would give you a daily income of approximately $145 at today’s prices. However, it is important to remember that these earnings are not guaranteed, as the price of Bitcoin and the difficulty of the network can both fluctuate over time.
