Maybe you thought you'd found the "one weird trick" indicator that was never wrong. Maybe you believed you could turn $100 into $100,000 in a month, easy. Or my personal favorite: thinking you could just copy some influencer's trades without any of the risk.
Well depends on coin or tokens you bought. I am able to gain buying $200 worth of public sale token of avalanche around September 2019 and sold that at $40k during bull run last 2021. Didnt catch the highest peak but the price I sold was still $100 from an entry of $0.5 per tokens.
So having some firm believed on potential of other tokens wouldnt be impossible. Yeah it seems delusional but if you know which will be good then it turns out to be a reality.
