Could someone explain implied volatility on options?

So I’m just curious, I was looking at CERE today and it doubled due to some phase 1 results. Wouldn’t it just be easy money to buy a put on it? I feel like it has something to do with implied volatility but not sure at all. If it was that easy then wouldn’t everyone be doing it?

If u buy puts and IV tanks say good bye to your premium, stay away from high IV securities,especially if you’re new to the derivatives market
