125k bitcoins is an 8th of a million bitcoins, which was around half a million bucks.
Aye, thank you, previous posters don't know maths.
Though it is unlikely there were enoguh buy orders holding at the previous 'price' to have absorbed all that at $500k in value. The 125k coins likely went for about $300k~ give or take $20k depending on what orders were in place to fill at the time.
