Most phishing links are designed with false purported benefits.
Sometimes we see links like this... click the link below to get 500BTC.
When you click the link, it will demand your wallet details, once you provide your details, your fund is out.
Nowadays, there is no scam offer like 500
BTC and offers like 1 or 2
BTC are good enough to make people greedy and fall to this scam trap. Offers of 1 or 2
BTC is more like actual offers and can have more chance of successfullying scam victims. It is more easily to find victims with offer like this but with offers of 500
BTC, it is like a fortune and chance to find too greedy and blind people as victims would be smaller.
Even offers for 1 or 2 Ethereum are enough as clear scam attempts. And scam like this appears and disappears with time, it will come back sparsely over time because there are always newbies in this market who don't know about it yet.
