Scammers are hacking youtube channels which have at least 10K subscribers to 80K! Then they collect some famous crypto meetup or interview videos! Later they make live streaming with that downloaded video, and announce a giveaway of 100K BTC or 100K ETH, BCH, XRP and so on! Can you imagine how smart this shit idea is? However, at the corner or left side of that live streaming they add a live transaction banner where you can see that if you send 1 Ethereum, you will get 5 or 10 Ethereum instantly!
If you ever fall in that trap means you are done, you fall in the scam and lost your money forever! Guys, be aware, always check a coin's official twitter handle to verify every giveaway! Don't fall in the scam, let scammers cry and die!
You dont ever have to check someone's twitter or anything. Big they ask you to send money to get money it's a scam...ALWAYS. If something sounds to good to be true than it usually is. Please dont ever send money randomly to "verify" yourself, otherwise you kinda deserve to lose it.
