Newbies are not expert in catching scams. As a matter of fact, they are usually the ones being preyed on by these scammers. So they will have to develop utmost caution. If they will have to generalize, then they should do it.
It is hard to investigate every single giveaway, investment opportunity, and so on. So for a newbie to avoid becoming a victim while still on the learning process, he/she will have to disregard all kinds of giveaways, investment opportunities, crypto bonuses, free tokens, and so on. And, most of all, they should never ever send any amount of money to anybody.
That's one of the most famous schemes that these scammers are using to fool newbies.
Also these newbies are easily fooled by doubling bitcoin, fake giveaways, and etc., that they think that it can double their money.
We should always keep in mind that it is much worth it if we really worked hard to earn money instead of relying on fake giveaways.
