Does the sharp rise in bitcoin price mean it will drop again?

Nov 03, I told my friends that bitcoin would rise up to $8000 this month, they thought I was crazy. Nov 09, the fork was cancelled. Nov 11~13, bitcoin suddenly dropped down to $6500, my friends came to tease me of my so called $8000, but I insisted on myself. It is Nov 17 ↓↓↓

Answer is, it depends. Almost every time facing fork, price will rise then drop. But if your focus is coming months or years, try to keep your btc and strategically invest, you will be surprised.
