The price may not have fallen 90% yet, but it may have corrected enough in terms of time
Assets correct in terms of price or in terms of time.
They either fall enough, or trend down for long enough.
The price hasn't fallen 90% yet, but it's fallen for roughly 14 months from the initial impulse move of the previous bull market:
There is nothing magical about the 14th month number other than it was the time it took for the 2014 bear market to bottom and slightly longer than it took for the 2008 bear market to bottom.
Which means...
We could be close to a low here even if the price hasn't fallen 90% from its highs like in other bear markets.
