Not new, people should be aware of these type of giveways already. Anything so called "giveaway" that requires you to send x amount of coins and receive xxx amount of coins.
I hope newcomers won't be blind enough to see and think about the possible outcome of this old scamming trick.
I hope so, but these type of people have the guts to take risks when they see that they will receive higher amount when then send smaller one.
