FSPM
FUSION PHARM INC
stockOTC

in 2013 I had bought 1000 shares of FSPM at .25/share. I had forgot about it due to moving across the country and other stuff. one night after the markets closed, I just happened to check and it was up to like a dollar or two. The next day it went up to over $8...i sold it at like $6...it crashed back down to earth after being at $8 for a bit. Found out when doing my taxes (at that time I was normally getting about $7500 back from taxes each year) that the money I won would be subtracted from my taxes...so that year I only got back like $1500...crazy stuff.
