Well...
Everyone makes mistakes. But only someone stupid makes the same mistake twice.
It won't happen to me again.
Thank God the loss is not so serious for me, because when the share was at €1.70 I had already sold at 80%+ and only reinvested the profit. It hurts trotzdem🤷🏾♂️.
Well, at least I'm rid of the headache for now and can continue to concentrate on my ETF.
