This depends on what you consider decent and also widely depends on the location within the country. But you'll be able to get a good house by my standards in most parts with the amount
Wow, indeed a very life changing amount. And I hope he doesn't blew it all away, and handle the money smartly. IIRC, there were such cases I've read before: people winning life changing amounts, but blew all of it in a few years.
You don't usually expect a gambler to make judicious use of their money where they are always looking for a way to double their money, of course a responsible gambler should be able to make used of their money. Anyone who are so much concerned to make profits doesn't know when they start losing heavily from their side because they would be intending of doubling their money without them knowing they are gradually losing it, from the value of that winning amount the said winner isn't meant to be poor for any reason or for any moments if they plans very well with their money.
Yeah somehow that's usual thing that will happen especially that the person who got that win got carried out with the system and think about that they can replicate those huge winnings they experience.
If he didn't discipline and maybe think about if he bet more bigger amount he can win more big profit on his next betting time. This is bad if he encounter bad luck since the casino would easily recover the win gotten by that player.
But hopefully those who win big time are smart to determine what is excessive for them and properly use their gains on right or more valuable means.
