The first leg down of Bitcoin in 2014 saw short volume candles until about the time when it made it's bottom with a true capitulation candle ($2 million on the weekly). Trade volume had just shifted into higher gear a few weeks earlier and was the start of the Great bull run. There was plenty of time to buy in at those low prices.
Also notice in 2016, Oct through Dec, the insane amount of volume became quiet all of a sudden. From that point on, BTC moved 2000% up to almost $20,000. This happened about midway through the bull run, but if it happens in a bear market, which we're still in, then look for huge drop in price instead, similar to the big volatility move we just had from 6000 to 3000.
