Many actually lose if there's a correction to happen. But you will not lose until you sell. For a holder, it's normal to see a correction like this but you have to analyze that if you've been in the market, you're still profitable. Can you give more meaning about the lack of market structure?
An investor should get into it if he/she sees a dip. We'll not know if after this we get to skyrocket again until it finalizes to break $40k once again.
Not to mention that FUDs are stronger during these times, some will be affected by it psychologically and many will do an action that is in accord with the FUD. I think what OP means with the market structure is the decentralization or the lack of similarity to stock market, I might be wrong but from what I have read, that is how I interpreted it.
