So on Bitcoin at least, I have been noticing this pattern in price and volume of currency traded. When the price is going down you will get a spike in volume, after which the price will ether stabilize or start going up. The spike is at least twice the 20 day average in volume. So when the price is falling you could wait for the spike and then buy. When the price is going up do your regular DCA plan. There does not seem to be any spikes connected to the tops of the market.
Any thoughts on this?
