Here's my personal Bitcoin prediction for 2021:

1. Some hedge fund will find a way to short Bitcoins.

2. Someone will inject a lot of illegal sh*t into the Blockchain. People already post images, e.g. https://cryptograffiti.info/

3. Authorities have to intervene, the price goes down, the hedge fund gets rich.

4. Lots of whining from people who didn't understand how Bitcoin works. Shoulder shrugs from those "in the know" who converted to regular money shortly before the fall.
