Waiting for Passenger Bus and bought NVIDIA stock

My Story in Bullet Points:

January 2023:
- I was waiting for a passenger bus to go to the office.
- At that time, I had around $10K in my trading account—just starting my stock market journey.
- As a deep learning engineer, I knew NVIDIA dominated the GPU market, but I had zero experience in due diligence (DD).
- On impulse, I decided to invest the entire $10K in NVIDIA stocks while waiting for the bus.
- It was a "take the risk and see" moment—completely unplanned.
My Trading Setup:
- I had two trading apps: one for short-term investments and another for long-term holdings.
- I used an iPhone 6s back then and never checked the long-term app regularly.
October 2023:
- I upgraded to an iPhone 14 but forgot to reinstall my long-term trading app.
- Almost deleted the app entirely from my life—it wasn’t on my radar anymore.
The Shock of a Lifetime (Last Week):
- A random thought hit me: “Didn’t I invest $10K somewhere? Where is it?”
- I re-downloaded the app, logged in, and was completely blown away by NVIDIA’s performance.
- The investment had grown significantly, changing how I view earning and investing money forever.

Now, I am thinking to buy more NVIDIA stocks in short-term account
