People just need to be aware that scammers always do anything just to deceive them so they should never fall on anything like asking money for a big profit returns since most likely this is just another scam in the making.
People should have a weapon against fraudsters, scammers --or what we call that deceive people just for easy money.
That weapon could be, knowledge and awareness.
If you have all of these you will never be their victim, they are just like prey waiting for a victim and most of them are naive people who lack knowledge. Airdrops and giveaways are prone to scams --if we join we must be careful or never join with these activities and keep in mind that there is no totally free money on the internet.
