Thats why we should not grab any giveaway like this. Those greed people never stop tricking other specially they are targeting those new in crypto. Some would lure you at the beginning but once you bite on their bat that will produce scammmmm.
The main target is the newbie. by taking advantage of their lack of knowledge and experience, the scammers make a profit. Usually the most common mode is to ask to transfer a certain number of coins with a certain nominal so that the airdrop can be claimed or withdrawn. luckily I didn't have enough money to claim, so I was able to avoid such scams. after that i started to learn a lot of things, nothing is really free, it has to be some effort or luck.
