I am no expert, but I was wondering if you have cost for small purchase of €25 for multiple shares. If there are costs per transaction, it will be a huge cost for small portion purchase.
@DerAzubi Over the last 20 years or so, $O has made more than Telekom, that's true, but nobody knows whether it will be the same for the next 20 years.
@noregrets59 his statement was about growth potential, which does not include $O. For your investment horizon, I would focus on future-oriented companies for individual stocks. Either something riskier (no gambling) or something like $V. But then you can also put everything directly into $VWRL.
@bettercall There are several brokers that charge you approx 1 USD/1 EUR per transaction but do have a larger spread. Some of them offer regular buys without transaction costs, just the spread.
