I don't know, what would be the interest charges on 10 billion per minute for being in my account...
At 5% interest, 1M gives you 50K a year. So 10B would be 10,000 times that, or 500,000M a year.
Divide that by 500 days in a year (I'm lazy), and you've got 1,000M a day. At 25 hours in a day (I'm lazy), that's 40M an hour. That's more than $600,000 a minute, which is $10,000 every second.
