It's either Elon's twitter account has been hacked again or another edited image circulating around social media.
Its edited ,I saw that in Facebook and I check elon's twitter the same day and no mention of that fake giveaway.they use that edited tweet to promote in other hacked twitter account and saying they receive it. so other people that following those hacked account will believe that its real giveaway which in reality its not and only want to stole other peoples bitcoins. BTW elons tweet edited the same day he mention doge on his tweet.
By checking the tweet history of Elon Musk, you can verify there are not any recent tweets regarding that giveaway. Therefore, it could be edited as there are similar tweets reported in the forum last year, which can be seen in this thread.

Thus, we should be vigilant in participating in any giveaway, especially on Twitter and Instagram which has been a place for a scammer to conduct their awful activities.
