You know, I recently thought about an interesting parallel that crypto traders often overlook. Most of us have heard of Black Monday, but few truly understand what happened there and why it’s relevant to us right now.

On October 19, 1987, an event occurred that shook the entire financial world. On that day, the Dow Jones Industrial Average plummeted by 22.61% in a single day. It wasn’t just a decline — it was a crash that spread across all continents. Markets in Europe, Asia, everywhere felt the wave of this collapse. People lost billions, and many still remember that horror.

Interestingly, Black Monday didn’t happen just by chance. It all started with an overvaluation of stocks — companies seemed expensive, yet investors kept buying. The problem was that many were taking out loans to make these purchases. When the market started to fall, people were forced to sell quickly to cover their debts. This created a snowball effect.

There was also algorithmic trading — computers programmed to automatically sell at certain price drops. Can you imagine? Machines were selling in panic faster than people could understand what was happening. Plus, high interest rates and international tensions added to the instability.

Now, here’s what concerns me. When I look at the crypto market, I see too many similarities. The volatility here is even higher than it was on traditional markets in ’87. We have periods when prices rise without apparent reason, then suddenly crash. And yes, algorithmic trading is also present — bots trade 24/7.

Cryptocurrencies are even less regulated than the stock market was back then. There are no protective mechanisms like those introduced after Black Monday. If a mass panic occurs, if a large number of people start selling simultaneously — we could see a crash even more severe than in 1987.

Fear is the main enemy. After that crash, people lost trust in markets for many years. And I see how this fear can easily spread to the crypto market if something serious happens.

How to protect yourself? First, don’t concentrate everything in one asset. Diversify your risk. Second, if you’re trading, use stop-losses — they help limit losses. And most importantly — don’t panic. When everyone around is losing their heads, staying calm gives you an advantage. Black Monday teaches us that markets can be brutal, but they recover. The key is to survive the storm without irreversible losses.
