Fraudsters, in fact, use the same deception scheme in different situations: they ask to invest a certain part of their money in order to get a large amount of money in the future. In whatever options this is manifested, you need to learn to resist the temptation to receive free sums and remember that this does not happen.
However, there will always be people who will voluntarily allow themselves to be deceived, so this type of fraud will always flourish.
