That was exactly my thoughts. To send Bitcoin, these "victims" would have to be very knowledgeable in it and technology. And have those thousands in their accounts with easy access. I know people with Bitcoin, besides myself, and we don't have that much money in Bitcoin. If we ever managed to have $1,000, it's for sure we wouldn't send it all in just because a Twitter post said we'd get double back if we sent it in. The "offer" was only for 30 minutes, it said. How did so many people with that much in Bitcoin know to look at these blue checked accounts right at that time these were tweeted, unless it was planned??
