From 2019, I got scammed in multiple ways. First drone parts and drones in general. Hyped on YouTube, and people make you think the last thing is great. The day I unsubscribed to 90% of the channels I subscribed was when DJI sent for "free" drones to anyone with a sufficient amount of followers, and mysteriously everyone began talking about DJI. Next scam was the corona virus, people wanted to make me think that I would die and should stop being healthy (e.g.: do sports, go outside, go to the beach) in order to be healthy. It didn't take long for me to figure out the scam since my father is a doctor and I experienced a similar scam 2009 (H1N1 flu vaccines scam). Next scam was "crypto". Everyone knows here so I don't explain further. At least in 3 years I got scammed multidimensionally so now I am less prone to scam, so thank you DJI, Fauci and crypto. I could add to the list some courses on Udemy but I didn't pay so at least it was just a negligible waste of time.
