It was my first time to see one "Vitalik giveaway" in Youtube yesterday. It was indeed ingenious to make it live and have fake chat comments saying they received the giveaways.
There are many scammers you used Vitalik's name as well, its not just a btc thingy, these scammers are going to use whoever they want as long as this personalities are really well known in crypto community.
I'm sure some newbie will fall for it, the Twitter scams make a killing before Jack Dorsey did something about it.
If you are referring to the Twitter hack incident, they are to blame and not btc itself. You just have to be very careful to not fall for this gimmick. And this kind of people are all over, Twitter/Youtube/Google. If this services slacks on how to prevent this on their platform, then we need to learn and educate on how to spot them early.
