There was the same type of scam used (also on Twitter) about two weeks ago I think.

Instead of the owner of Binance, they impersonated Elon Musk then.

The scam was identical regarding the "giveaway", ETH and amounts.

The scammers just use a viral situation, knowing people will be highly interested to follow certain events or people right then, and won't pay attention to details (like who is really the Twitter account sending the tweets).
