As the jackpots grow for the Powerball and Mega Millions lottery games, so to do people’s hopes that maybe — just maybe! — they’ll be the lucky one to win even just some of the hundreds of millions of dollars at stake.

After all, what could be better than winning the lottery? The overnight rags-to-riches dream is understandably a fantasy of many, no matter how much of a statistical longshot it may be.

And of course, the news cycle has no shortage of stories about people whose lives are irrevocably changed for the good when they encounter a massive and unexpected windfall of cash — yes, even here at USA TODAY.

“The lottery, especially when it’s really big like this, you’re walking around town and people are talking about it,” said Kurt Panouses, a Florida lawyer who advises winners of big lotteries. “There’s a lot of hope that people have — people are dreaming right now all over the country but unfortunately, there’s only one winner, if there is a winner.”

But if you’re one of those people lucky to win either of the jackpots — an estimated $1 billion for the Powerball as of Wednesday, and $720 million for the Mega Millions — you might find your past financial problems replaced with new ones.

Panouses has seen it all in his years of representing upwards of 40 people across the U.S. who won $1 million or more in state lotteries.

If they don’t fritter it all away on bad investments and extravagant purchases, Panouses said those who win that kind of money may find themselves the targets of scammers, harassment from friends or even complete strangers, and — in extreme cases — those willing to kill.
