Every four years the amount of Bitcoin issued every 10 minutes gets cut in half. The reward for the miners suddenly will be half over night, but the amount of energy used remains the same. Less supply, same demand, price goes up, compensates the cut to the miners.

With all due respect. Before thinking in mining, I recommend to put at least 20 hours of study.

Start with the Bitcoin Standard.
Watch at least 6 hours of Micheal Saylor videos, specifically those about Bitcoin as digital energy.

On the website of Arman the Parman you will find very didactic content.

Try to understand every sentence of the rap video of Tip_NZ in Twitter, Down the Rabbit Hole. 

Ask questions here, everyone is really helpful

Please forgive my ignorance, but what is this halving event that will occur in a little over a year?
