Bitcoin's price staying above the 50-week moving average indicates a bull cycle, while dropping below it signals the end of the bull cycle and the start of a bear market.
"Ben noticed is that when Bitcoin is in a bull cycle, it's always stayed above that line. But when Bitcoin's price goes below that 50week moving average level, that marked the end of the bull cycle and the beginning of the long cool off period. That's what people call the bare market."
