There is a strong motive for scammers to make a scam as they become greedy with the increase of Bitcoin's price. But I think it just a coincidence as they found some exploit on twitter and social media to carry out their bad deed.
the fraudsters also use this hysteria to lure newbies and cryptoenthusiast who are careless, stealing money with increasingly neat and varied motives. like the case of the hacking of the company and influential people in twitter official account a few weeks ago. we absolutely cannot trust any give away that requires you to make a deposit first, then it will be returned 200%. I once said this to the cheater that my DM was telegraphed: "I don't have money to deposit, what if you give me 50% of it?"
lol
and the cheater is no longer replying to my chat.
so, be careful ... keep using logic and don't be easily provoked.
