Well, dont sell with emotions, read, analyse and think about it first. It's true that btc has been falling, part due to the SEC decision at this moment, but that is something that happens even fiat currency. Look at Turkish Lire for example.
If you have a defined strategy, try to stick to it, don't panic sell just cause it's falling (unless that is you're strategy). And if you look closer to this, even it all those drops, big companies around the world such as financial ones ( banks), power companies, tech companies etc, all didn't stop the projects and investments in the blockchain and crypto adoption.
