This is a simple Java program that simulates Bitcoin mining. It generates random numbers and if the sum of two numbers is close to 1, it increments the Bitcoin count.

1. Creating Random and Scanner objects: The program starts by creating a Random object for generating random numbers and a Scanner object for reading input from the console.

2. User input: The program asks the user to enter the time they want to wait for mining Bitcoins.

3. Initializing variables: The program initializes a variable to keep track of the number of Bitcoins found and gets the current time in milliseconds.

4. Mining loop: The program enters a loop that continues until the specified time by the user has passed. Inside the loop, the program generates a random number. If the absolute difference between this number and 1 is less than 0.01, the program increments the Bitcoin count by a random value multiplied by 2.

5. Displaying results: The program displays the number of Bitcoins found so far.

6. Closing the Scanner: Finally, the program closes the Scanner object.
