0.0001 to 0.0017= 1600% percent gain aka 17 bagger Example: if a stock went from $10 to $20 you would have 100% increase and $10 to $30 = 200% percent gain. I see many examples on stock forums where they would say 0.0001 to 0.0017= 1700% but you have to subtract your cost basis of 0.0001 so the percentage is reflecting your gain not the mathematical multiple.
