I saw you spammed the forum with two topics about your win.
First topic:
https://bitcointalk.org/index.php?topic=5425205.0Second topic is this one.
I recommend you to choose one of two topics to use for your discussion and lock one of them. This topic in Gambling board is good to keep, the one in Beginners & Help should be locked and even move to Archival board - use the move topic button at the bottom left corner.
If you won big like this and successfully withdrawn, with approval from Stake.com, I believe that they will not keep it in secret. They should announce it publicly because it is good for their reputation.
Why I did not see anything from Stake.com?
The first topic is asking what I should do, ideas, and what not. Also, I did have a successful withdrawal, They probably have over 10 1M+ wins every day, Don't know if you know this but stake is valued at over 1.5B. I would love to get featured by them, But I don't know if they would want to do it. There are stories where people turned as little as 10$ into massive amounts of 500k-2M and they didn't post it, Part of that is the user's privacy. Nonetheless, I love stake and have a lot of respect for them.
