I just realized that many people still don't fully understand what a crypto bubble is, especially those who are new to the market. Today, I will share some of my observations about this phenomenon.

Simply put, a crypto bubble occurs when the price of a certain cryptocurrency or project skyrockets in a short period, but in reality, market demand does not match its true value. It's like a hot water balloon—gradually inflating, then growing larger, until it finally bursts. At that point, the last buyers usually suffer heavy losses.

Why does a crypto bubble happen? I see a few main reasons. First is FOMO—fear of missing out. When prices rise, people rush in to buy without doing proper research. Second, excessive excitement causes people to ignore the technology or practical applications of the project, only seeing the rising price as "good." Third, social media and influencers promote heavily, making it easy for people to be swayed.

Looking back at history, there are two major crypto bubbles that I think are very instructive. In 2017, when the ICO (initial coin offering) became hot, many new projects issued tokens to raise funds. At the same time, Bitcoin also surged, and everyone was investing in projects with no guarantees. The result? Most disappeared, and investors suffered losses.

Then, from 2020 onwards, DeFi and NFTs suddenly became extremely popular. NFT PFPs like Bored Ape Yacht Club and CryptoPunks reached prices in the millions of USD. People spent hundreds of millions on small images, believing prices would keep rising, but then the market crashed, and most NFTs lost huge value. That’s a classic example of a crypto bubble.

So, how can you tell when a crypto bubble is forming? I have a few warning signs. If a crypto skyrockets in a very short time, be cautious. If a project has no real technology or application and only sees price increases, that’s a red flag. If you hear from media or KOLs that "buy this, the price will go up a lot," be alert.

But what’s the best way to avoid falling into a crypto bubble? First, do thorough research before investing. Learn about the team, technology, and the problem the project aims to solve. Second, avoid short-term trading—buy during dips, sell quickly for profit. Think long-term and only invest in projects you truly trust. Third, don’t put all your money into one crypto. Diversify your portfolio across different sectors.

Finally, when prices rise, consider taking some profits. This helps preserve your initial capital, and even if the market crashes later, you won’t lose your principal. That’s how I manage risk when participating in the crypto market.

In summary, a crypto bubble is a real phenomenon in the market, but if you are careful, plan well, and don’t let emotions control you, you can protect your investments. Always remember: do thorough research before making decisions.
