A resurgence of scam campaigns that pretend to be Bitcoin and ETH giveaways from Tesla, Elon Musk, and John McAfee are underway. These scams are promoted through Twitter accounts that impersonate Elon Musk and other celebrities. The scam pages will show a pool of cryptocurrency with an indicator of how much cryptocurrency is left to giveaway and a live streaming list of transactions. These indicators are shown to make it look like many people are taking part in the giveaway. This also acts as a goad to get more people contributing to the giveaway before the available pool of free cryptocurrency runs out.
