Let me tell you why this huge drop happened, the Bull Run has already started and it's already happening. Millionaires are about to invest all of their money into Crypto now.
What they did is this was done somehow on purpose so that they can buy as much Crypto as they can these days, before everything is about to rocket on about at least 500% - this is just my own prediction and not an investment advice.
If you use Bitcoin as a seller, as i do, i would run a promotion and give people up to 80% OFF if they pay me in Crypto (at the moment), even though you get 20% only, this is about to grow way lot than what you would be getting in cash currently. The moment you start feeling happy about what you have gotten so far, just cash out everything and think of investing in something not as risky as this is, but basically, this is the long story short of what is now about to start happening.
Rich people will probably triple their money in just a few months, while the poor will still end up loosing way more than they can afford. True story.
EDIT:
Forgot to add that when you are a seller, it's high likely you will spend at least 75% of your revenue on stuff you love, leisure, etc. but if you get it in crypto, it's just a chance for a successful investment with money that you were about to spend like you would normally do.
