Can someone fill me in?

I am into bitcoin. I was moving my retirement into MSTR and FBTC and I had some money left. I searched for companies putting bitcoin on their balance sheet. I saw GNS and it was like .60 so I bought some. Then I got an injection of money so a bought a lot. Then I found this sub and learned of the shorts. Also found out about the rights. Anyone want to fill me in?
