This and it matters when you want to cash in your gains or cut your losses. If you have a short-term investment strategy the drop is super-scary and if you're over extended in crypto you've done it wrong. If you think long-term a drop like this is disheartening, but nothing to lose sleep over. It's a very volatile asset and crashes and bubbles are practically guaranteed. If you don't need the money tomorrow, hold it or even buy when it's low like now.
