BTC is "Sell in May and go away" reasonable? In Bitcoin's history May ranks: - 6th best month in average return - 3rd best month in median return So while there definitely have been sell offs at times (primarily 2021), overall there is no clear seasonality to support this saying for Bitcoin. What is true is that starting may and going into the summer generally kicks off some months of lower volatility and price action.(Daan Crypto Trades)
