What’s the best way to cash out without creating a huge ruckus?

For example, lets just say that I theoretically put $4000 into crypto, watched it quadruple and now I theoretically had $16k in crypto.

Now lets imagine that I theoretically put half of that so $8000 into this funny haha dog coin called Shiba Inu or something in August 2020 and just forgot about it cause it's funny to put a lot of money into stupid jokes.

But theoretically lets say that it turned to $8 billion in a bit over a year and now I want to cash out and move it to my bank account. How would I theoretically go on about this safely if I theoretically had this much money in crypto, in theory of course.
