Doctor was won around 500BTC in Bitdice (More than this winning) on 2 years ago or so.
I did not know BitDice is already 2 years old. Was it on same website or that was renewed?
Oh, it was at Dec 2, 2015 when alex posted it (It should be around 1 year+). Here
https://bitcointalk.org/index.php?topic=1273407.0Yes, it's Bitdice. It was happened when Bitdice still at V3
Mathematically Wonton's 300btc is bigger than Doctor's 500btc. Doctor won it on December 2015 when the price of bitcoin was around $ $350-450, equal to $175,000-225,000 while Wonton won 300btc last month when the price was around $800-950 = $240,000-285,000.
Both winnings were still great amount though and good thing is that both were legit winnings on legit site. Bitdice is rock...
