My crypto mistake in 2016 cost me about $6,850,000 with current prices. What was your worst crypto mistake?

No Cap Invest checking in with my oopsie.

I discovered Ethereum when I was 19 still in college. I tried mining it but didn't succeed. (Nowadays I'm mining $2k a month and I'm building a solar powered bitcoin mining farm. I know, just like vosk.)

ANYWAYS

I bought an ethereum mining contract for $300 when Ethereum was at $0.07.

I got basically nothing in return, and had I just bought instead, I would have 4,285 ETH. Or about $6.9 million dollars.

it messes with me every day, but I learned my lesson. After working for the largest bitcoin exchange in the world for over a year, I only grew even more in love with blockchain. it keeps me up at night. I catch myself day dreaming of the possibilities and applications, and how things will develop geopolitically, philosophically, and of course, technologically.

EDIT: When I said 'it messes with me every day' I don't mean I'm suffering. I'm doing great and its probably the best thing that ever happened to me, as it lead to me to learn more and eventually get a job working at a crypto exchange. Yeah it sucks but that's life, can only keep your head up and keep going.

Edit 2: To all the people saying that i would have sold at 20, 30, or 100k: i bought and held btc before that and still have not sold. i have about 10 altcoins that i hold and earn interest on through DeFi. So knowing myself, its highly unlikely. I even went and sold some of my btc and bought more eth so i ended up having several eth, but not thousands.
