Are you from the Stake.com team maybe?
There is a second giveaway thread in this section from Stake.com
Stake.com $250 giveaway #3!, but it seems to be not active from July.
I tried to contact OP and Stake.com support but never got any answer.
i think that giveaway still active and as you can see in the thread that you must guess the 5 winning number for you to win the prize
so if there is still no update then until now there is no one guess the top 1 and 4
