Grayscale: The increase in Bitcoin's price is highly concentrated on a few trading days, and staying out also carries an opportunity cost

Grayscale's research director Zach Pandl stated that over the past three years, Bitcoin's cumulative return rate was approximately 225%, while the Nasdaq index's return rate was 109%. However, Bitcoin's rise was not evenly distributed, with a few of the strongest trading days contributing significantly to long-term returns, increasing the difficulty for investors to time their entry.

Data shows that if the five best trading days for Bitcoin are excluded, its three-year cumulative return rate would drop from 225% to 95%; excluding the best ten trading days, the return rate falls to 27%; and if the best fifteen trading days are missed, the three-year return would turn into a loss of 11%. In contrast, the return distribution of the Nasdaq is more balanced; after excluding the best fifteen trading days, the cumulative return rate drops from 109% to 21%.

Grayscale indicated that during this period, less than 0.5% of trading days contributed enough gains that, when excluded, would reduce Bitcoin's cumulative return by more than half. For assets with high return and high volatility characteristics, staying out also carries an opportunity cost; since the best trading days are difficult to predict reliably, waiting for volatility to decrease or for market prospects to become clearer may mean that some price re-evaluations have already been completed.
