The best time to start is always today! Time is one of the most important factors when investing. The longer you invest your money, the more you benefit from compounding and the better you can ride out potential market fluctuations.
Nobody can tell you for sure how the markets will develop. Waiting for the right moment is therefore not advisable. Just start with a small amount and find out under which circumstances investing feels best for you.
At the moment, the markets are not looking very promising due to political and economic developments. You may feel that it is not a good time to start investing. But the opposite is true. For example, you can currently buy more stock ETFs for the same amount of money than a year ago. Think of it as if investment products were on sale! Also, don't be discouraged by the fact that your investment account will not show any book profits at the beginning. That's how all investors feel at the moment. History shows that after every crisis the stock markets have recovered. Just think of COVID or the financial crisis of 2008/2009.
