Seeing how real revenues are in the distant future (PTK now below $0.20CAN), thought I'd mention some revenues from the marijuana industry.
A few of the top companies are bringing in $10-15M per quarter selling low overhead, low technology, product grown in greenhouses. Some of the middle to low tier companies have $30M+ cash in the bank.
Canopy has revenue of $14M last quarter and roughly $100M in cash.
