About two thirds of bets are for NO and I guess the chance to see $20,000 dip is possible. Price often moves to what most of traders,  investors, gamblers do not think of. It is the game of faith, risk management and manipulation. If I was a whale, I would make a plan to dump bitcoin back to $20,000. I have more belief to do it if I look at the NO bets.

I zoom out and in the bitcoin chart and see that in 2017 bitcoin has a big fall before the parabola rise. If bitcoin falls back to $20000 and tops up months later at $20000 x 20 = $ 400,000, will it be great?

x20 is the increase of bitcoin from 2013 all time high to 2017 all time high.
