Advance congratulations to whoever will ever be chosen with this giveaway. This is an obvious sponsored post for her by cashapp.
It's seasonal to see such ads with the pump of bitcoin. Exposure, interest, and adoption are the main goals for this and to cash app, they're attracting more users to register into their platform.
That's their marketing and advertisement technique but an expensive budget has been allocated.
I thought this is just a scam or something. Hopefully, this one is not and that all that tweet has something to back it up. $1 million is not really that big amount for CashApp, considering they got Megan Thee to advertise the promotion. CashApp as far as I know has a lot of users around the world and I agree that it will be a big exposure for bitcoin as a whole as most of Megan Thee followers if I am ever allowed to judge, ignorant about bitcoin.
The account has 5M followers so it's a sponsored tweet/post for her paid by cashapp. She's also directing joiners to cash app.
This is brand endorsing by this influencer, I don't know her but if she's putting people to cash app, there's only one reason for that.
