I never trust this kind of events. It's obvious that it's not safe. Hackers captured even Elon Musk's Twitter account and swindled many people. Do not trust everyone! There are frauds everywhere. This is a very simple trick.
Am still very surprised people still fall for these cheap scams, for Godsake there is no free money in crypto, gone are those days we easily earn money from airdrops and giveaways, it's time people learn to be more careful else they will keep making these guys rich by giving them their hard earn bitcoin all in the name of bitcoin doubling.
