The 40000 might be Suprnova, 1% of what was mined there. Or was it zero fee?
The 40,000 was around 14k. Two days ago there was a clown who had his whole stack placed as scarewalls, Mr. 40k bought the scarewall at around 45k and placed a 10btc floor at 50k, got dumped another 6btc and that's the story behind the 41k wallet. Numbers are a little off but that's basically what happened.
TL;DR the bear clown got raped.
