September is historically the worst month for the bitcoin price, but it may be about to close its best yet. BTC ended September in the red in eight of the past 11 years. This year, it looks set to close the month up by at least 7%, even with today’s swoon. The bullish month puts bitcoin on a strong footing going into October, which, by contrast, is one of its strongest. Where September has seen an average loss of 3.6% since 2013, October has seen average gains of 23%. Some traders are targeting a run to as high as $70,000 in the coming weeks. A green September has always resulted in bitcoin closing higher in October, November and December.
