I see all of users are congratulating OP can get huge amount money in instant way and fast. Anyway, if it's true congratulations! 
i didnt see he said that but congratulate is the right word to say when someone wins or get lucky on something 
so i also like to congratulate him . no one talking about the address provided from OP is true or not. It's very possible if OP using other people address since we can't verify it, unless OP can sign messages from that address. No offense from me, just my opinion.
i read that there are users on the first page that checked the address . he said the address had many transactions but like you said we still dont know if the owner is really him . having many transactions could be the reason why he got lucky to win such prize but he also spend so much money in the process . anyway that all still paid off and he dont know that what if the coins value can still rise in the future .
