$24,000,000/10,950(365days per year * 30 years)= $2191.78 per day of spending. That would be $15,342 per week and a measly budget of $61,369.86 per month. He/she could have probably retired on that even with zero earnings on cash and inflation.
Who gets it now?
The hardest part of being a drug kingpin isn't how to smuggle the drugs, its what to do with millions in cash. A guy can only pay cash for so much stuff before you start raising red flags. Money laundering and tax evasion is what gets most of these guys put behind bars.
Watch the "Cocaine Cowboys" documentary about the Miami drug trade back in the day. Good Stuff!
I'd find a way to spend it.
