Hold Telekom shares or realize profits 💯

$DTE (-1,7 %) Almost 50% of my portfolio consists of telecom shares. I have held these since 2016, when I bought them at 7 euros eppes, so they have performed brutally to date. Should I continue to hold them, also in view of the dividend, or should I sell some of them? I currently hold 1000 shares. I'm asking because I actually want to diversify. However, the initial investment was small. Thank you all already. The app here is really great. Lg Dirk
