It seems like you are not the only one. CDPROJEKT has been the top 1 biggest company by trading volume on the Polish sotck exchange over the last few months. It even surpassed the second biggest copper producer (KGHM) in the world.
As an aside, I'd advise you avoid brokers who advertise like bookies.
Yet somehow I managed to only earn 30sth % in 2 years by daytrading instead of holding :)
