Now they are both in freefall and I'm considering an entry point.
To avoid catching a falling knife, the first thing you or anyone who's interested in a project that's dumping should do is to quickly rush to any social media outlet of the project to find out why the dump is happening and if there's any internal scruples. You can't miss this if there's anything wrong going on. Someone on the media channel is bound to expose it. Don't rush to buy any coin because you feel the price has depreciated. Find out why first.
How do you decide where to take the plunge? A certain %drop from the top or a %above bottom?
I do random buying using the DCA technique.
