The only way to be safe from a huge loss after that much winning is to go offline directly or take the whole fund and go underground for some time. The thing is, the sudden huge amount creates a lot of pressure on you, facing the greed and the relatives that come after hearing of your win is the worst part. However, if I can get it, I would use it as soon as possible, paying off the debt, making my dreams come true, making some investments for the future, and spending on my own. The rest of the money will go towards buying a car. Of course, the sudden huge amount will change my behavior, but I will manage it the way I manage how to spend it safely.
Some people feel motivated and develop so much interest in using their wins to gamble in order to get more profits, especially those who are desperate to become as a result of gambling despite seeing some people running bankrupt as a result of that same gambling. A gambler who is wise will use that huge win to start a life from different angle, rather than putting it back into gambling. The best thing to do is to invest the money in something that is beneficial and productive to ensure that gambling never hit you hard.
It doesn't always work that way. Ask those who spent their money after winning and they will tell you that the pressure was too much on them. They had friends, family, strangers and themselves to settle. Reality dawns on the winner after the money is almost finished. The fact is, if you do not have a plan, you will bow to pressure no matter how careful you try to be.
I have never won a jackpot before or any huge win at all, but I already have in my head what I will do with my money if I suddenly get blessed with a lot of money, whether through gambling or not.
Every gambler should carry that kind of plan in their head at all times. Luck may shine on them one day and they will be glad that they already had everything mapped out for themselves.
