If you have won 10,000 worth from lottery,
then I`d say you are very lucky.
It may seem kind of small as compared if you could have won a million but of course,
it is still considered lucky to have a 10,000 in an instant.
As for where to put your winnings,
your broker may have suggested for you to invest half of it in gold but of course,
you should be aware that at the moment the price of gold has declined.
Should you have invested half of it 6 months ago,
then you could have earned roughly around 13% already.
But of course,
it is still your choice if you are going to put half of your winnings in it.
you could place only a portion in gold then put the rest in mutual funds as well as in savings.
At least the most important is that you are diversifying your money.
