The cryptocurrency world is very deep, probably because it belongs to a gray area that is difficult to regulate by law, which leads to the presence of many scammers and scams.
Brothers who have participated in new token offerings may have encountered situations like the one in the first image, where they find an inexplicable record of sending BNB, and even the address they sent to is very similar to one they used before. Upon closer inspection, it turns out that they actually sent fake BNB to a fake address that closely resembles their own address, with the aim of tricking them into mistakenly sending coins next time.
Then there is the situation in the second image, where they receive inexplicable tokens, and the name guides them to his website. I have never visited the website he provided, but it is likely to deceive you into granting authorization and then steal your wallet assets.
The above is what I know about airdrop scam prevention knowledge. If you know of other tricks, feel free to add them.
