While I know why you think entries are more important they're really not.  Trading is about minimizing risk and properly managing trades which you can do at any entry point.  Obviously buying at the lowest point is prime but you're more likely to win the lotto than to do that on any regular basis, and since your profits or losses are realized at exit, it's possible to buy at the lowest point and get taken out for a small fraction of your potential profits on a retrace with bad trade management or set a stop too close and get taken out for a loss before it runs. 

That being said, In regards to my discretionary trading, yes I still have to enter before I exit so to answer your question I suppose I wait for reversals since that's usually where I find value.   That being said, sometimes markets just chop, build up steam, and pop so really what I'm looking at is orderflow. . . and no, I don't listen to experts.   Most of the experts I find breaking down crypto markets are using outdated tools I don't trust (moving averages, bands, oscillators, etc).
