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.
Yet somehow I managed to only earn 30sth % in 2 years by daytrading instead of holding :)
As an aside, I'd advise you avoid brokers who advertise like bookies.
