Now that it's a bear market - people feel like it'd never go up again.
The current state usually always feels permanent but of course, never is. Nobody knows if we're gonna go up or down but we do know that no state is permanent.
True and a lot of people have extreme difficulty timing their entries and exits so both scenario's are often exegerrated by Fear or panic. But then again, even if it isn't permanent you don't know how long it can last. I doubt many have the patience to hold trough a 2 year bear market with constant decline. Its best to know when to exit and get back in so you don't have to suffer.
