We have to be very careful when we see the email and delete it immediately if we don't know anything and it's better to visit the site and ask further.
But usually, if someone has won money, they will start to think that the casino site is safe and they can continue playing there.
There is a way that may be safe to avoid losing a lot of money, and that is by not using a lot of money to gamble so that if the site has problems, we will not lose too much money.

Before we decide anything, it's better to research and wait a bit to avoid the scams common to people who do not search for anything.
Maybe it would be better if we invest in coins that already have names like bitcoin, ethereum, bnb, and others.
