Depends on the wave. Wave 1 is typically difficult to predict. Wave 2 is a little easier. Waves 3 , 4 and 5 are generally the easiest to predict, as you've got prior movement on which to base a target.

The problem is, there's a great deal of manipulation taking place, making crypto the single most difficult market to predict at the moment. Elliot wave is great in an "honest" market. Crypto is anything but right now. That's why I spend so much time on other technical indicators. Still, elliot wave is a decent tool to use in combination with others.
