No one can ever say how long bear trend will last. To give you an example, we've experienced the longest bear market from last year until March if I'm not mistaken. Though there are so many speculators that the bear will gonna end in some time but never actually know when is that exact time. The corrections are already performed and I saw bitcoin today at $8,900 going on $9,000. So, the bear will never last in crypto market. Just some recoveries after the bear.
