The largest crypto group on facebook has taken a portfolio from 10K to 75K in 8 weeks through group voting
Heres the doc: https://docs.google.com/spreadsheets/d/1kZFXoHhHvt4kd225aoqlNHZnSfQhcnoZutnKDXkqmJ0/edit?usp=sharing
The group is "Cryptocurrency Investing" with 100K members

This is interesting though it seems market manipulation like this may be the target of regulation.
The group voting is done weekly and votes are re-allocated
