Betting against the crowd: a coin flip
A popular belief in crypto: “when unusually many traders bet on a rise, the price falls.”
The data: 125 such moments on a basket of coins. Within 3 days, the price dropped first in 51% of them and climbed first in 49%.
A coin flip. A crowd shows where the bets are, not where the price goes next.
Would you still bet against the crowd?
