By 2020 I think you get to that $10 pps only by merger, acquisition, a big board listing [NYSE] and a completely different legal environment including fully legal banking and much larger number of states with recreational cannabis legal.
Otherwise I think $10 pps is a bit optimistic even by the end of 2020.
I of course hope you are correct and I am wrong! lol
The way things are rapidly developing it really is hard to estimate a pps other than to say if you are already in, your chances of a multi bagger by 2020 are looking very good :)
