September is typically a bear market month for cryptocurrencies and other asset classes, but October has historically been strong, according to a new analysis from QCP Capital, which showed bitcoin posted positive returns in October in eight of the past nine years, with an average gain of 22.9 per cent. This seasonal pattern may explain the recent continuation of bullish buying in the options market, with 150 call options expiring in December at a call-over price of $80,000 again observed in Asian morning trading. QCP suggests that investors may accumulate bitcoin during the September pullback and settle at a profit in October or at the end of the year.
