IMO, Aside from the desire to get rich quickly, large profit offers are also a common problem. Not just on crypto, isn't it? With any cases that occur in the real world, such as fraud through e-commerce, ore similar cases that already broadcasted on TV, it should have provided education directly to all people to be careful and not believe in similar offers like "1000% profit, 100% money back investment, 100% profit for a week, double your money quickly, etc". However, giveaway traps people very often and it's works, because victims see this as an opportunity to try something they have just seen. Not because they do not understand, It's happens many time.
There are lots of fake investments in the real world with Fiat case, they assume "if you don't try, you missed the opportunity". In the world of sales, sales give an effort by adding "urgent" factors to their customers, one of them using offering words like "only today, special price, etc". This strategy then makes someone to think of doing something shortly to buy the products. Which in my opinion they are caught in a scam because of something similar. They rely on offers and profits not just because uneducated or doesn't have knowladge. Another factor, not doing research before they are make a decision to invest or buy shitcoins. If they are learn from this case, maybe they are will be more careful about any investments offer.
