This will take some time to get. I suggest upgrading your "Financial Investments" and "Business Investments" to help get there quicker. Here are the values of the money in the game:
1K = $1,000
1M = $1,000,000 - achievement
1B = $1,000,000,000 - achievement
1KB = $1,000,000,000,000
1MB = $1,000,000,000,000,000
1BB = $1,000,000,000,000,000,000 - achievement
1KBB = $1,000,000,000,000,000,000,000
1MBB = $1,000,000,000,000,000,000,000,000
1BBB = $1,000,000,000,000,000,000,000,000,000
This is the money you have on hand and is NOT cumulative.
