I don't look at my wallets that often because I start digging to find out what is causing the rise or the dip and that is a big distraction. I understand that there were companies that take out futures on Bitcoin and when CME went online just when bitcoin hit $20,000.00 that's when the market started to tank as well.
We know that huge orders for paper gold can move the price by $20 in a second. These orders often exceed the CME stated limit of 6,000 contracts. Here’s a close view from October 31, when the sale of 2,365 contracts caused the gold price to plummet and forced the exchange to close for 20 seconds:

My curious cat mind wonders if this is true for bitcoin as well....
