What is #二元期權 ?

In simple terms, binary options are "$BTC ultra-short-term financial derivatives". It sounds like an investment product on the surface, but is it really just a legal way to guess price movements?

"Binary" → There are only two options: Up (Call) or Down (Put).

Investors bet on whether a certain asset (usually forex, gold, stock indices, etc.) will rise or fall within a very short period (30 seconds, 1 minute, 5 minutes, etc.). Once the time is up, the settlement occurs immediately:

If the guess is correct → A fixed return is received (for example, if you bet $100, with a return rate of 80%, you get back $180).

If the guess is wrong → The entire principal is forfeited (goes to zero).

It is different from traditional options as there is no "holding until expiration, exercise price"; it is simply a quick guess of "YES / NO" for price movements.
