The fake Elon Musk BTC and ETH giveaway website, muskbtc.su, is a scam. The scammers operating the fake website trick visitors into sending them cryptocurrencies by claiming they will get double the amount sent back to them. The scammers also claim that visitors will get a chance to receive a Tesla Cybertruck Custom Model, shipping included, if they send cryptocurrencies in the amount of 1 BTC or 20 ETH. But, if potential victims send the cryptocurrencies, they will never receive what they were promised and will not have their cryptocurrencies refunded.
