do you think it is important for gamblers to have a do list in case they win a huge amount, and what are the first steps they should take?
gambler or not, people should at least have a list of things on what they will do with the money. it's a common thing to have if you value your money and want to save as much as you want.
anyway, if the winning amount is very big(I mean, lotto jackpot big or millions dollars win in gambling) it would be best for them to hire a financial advisor, they'll know the first steps you need to take to secure your money and they'll give you advice how to manage it and how to properly invest it.
