As long as there is a greed in the people. the scammers will exploit it and make people poor. We need to understand and use common sense when participating in these giveaways.
Greed often covers logic...
who are not interested in the benefits they provide, if they are not able to control themselves then they will fall into the trap of deception. Honestly, I used to almost fall into a fake giveaway trap like this, but I was lucky to have a husband and friend who reminded me to think more critically and logically because it is impossible for anyone to easily give their BTC easily.
