Actually after the first 500 contracts, there were another 900 contracts on the 30 strike and another 700 contracts on 30.5 and 31 strike. The prices of those contracts were around 0.15-0.20. That means that someone spent ~30-40k on options that had 80%+ probability of expiring worthless the next day. Someone still thinks it's a coincidence?
The only coincidence is when something intelligent gets posted on et and I'm not the author. PS I declare victory in the war on btc. 99% of anyone speculating in btc and its illegitimate offspring has lost money.
