5 Minutes in the Pool of Terror for 5 Billion?

A genie gives you an offer of 5 billion dollars for 5 minutes of your time.

The genie explains that your opportunity to win will require you to spend 5 minutes floating on the surface of a massive pitch black arena pool that is 1000 feet deep and half a mile wide by half a mile long. In this pool is a 300 foot long giant squid that if it senses you, will attack and eat you. The squids spawning area is random.

Do you take the offer?
