Hindsight is always 20/20. If time could rewind, knowing what I know now, I would've just went all in into $NVIDIA Corp(NVDA)$. However, I let my emotions get the better of me and kept waiting for it to drop to a more appealing price, which it never did. As a result, I was only able to buy a few of them.
My biggest investment loss ever would be $Lucid Group Inc(LCID)$. Lesson learnt to not just follow the EV hype without properly researching the company and its fundamentals
