Do not panic sell!
Well that was a massive and sudden drop for Bitcoin. Anyone who bought today and is starting to panic, don't. Hold on, these drops are common in Crypto land. Remember you are investing for the long term.
After such massive moves we are bound to have a drop, a couple of things might be happening here:
1. Profit taking
2. Whales shaking the market down
Anyway. Don't worry. Have a beer. All will be fine.
