The crypto world is full of ups and downs. Those who see opportunities clearly can make money, while those who don't just go with the flow. To avoid being eliminated, you first need to understand what constitutes a certain opportunity and what is an uncertain opportunity, and then you can discuss sector classification.

**How to play certain opportunities?**

Simply put, certain opportunities are those events that are already guaranteed to happen. Take the 2026 World Cup, for example. The dates are set—June 11 to July 19. Since this event is definitely going to happen, the sports sector is worth paying attention to. There are five months until the World Cup, and the hype around sports concept coins is gradually increasing. Historical experience shows that during every World Cup, the sports sector experiences a wave of market activity, and this time will be no exception. This is what is called a certain opportunity—since it is guaranteed to happen, you can position yourself in advance.

**What about uncertain opportunities?**

Now, let's look at uncertain opportunities. For example, the listing of OpenAI on the US stock market. We know it will eventually go public, but when exactly? Will it be delayed? These are all unknowns. Once the listing date is confirmed, the AI sector in the crypto world is likely to see a surge. So, the focus isn't on whether it will happen for sure, but on closely following its latest developments and trying to get on board before the market takes off.

**Sector classification is fundamental**

In the rapidly changing crypto market, if you can't distinguish between sectors, don't expect to make stable profits. Each sector has different characteristics, and their rise and fall rhythms vary. For example, the DEX sector has only a few core tokens—HYPE, ASTER, and LIT are the top tier, representing the main flow of the sector. Understanding these will naturally increase your chances of making the right moves.
