Your worst crypto mistakes

I go first:

Had three BTC and sold them 2018 mid crash for a 7k $ profit. Really thought crypto is over and BTC death forever this time and didn‘t believe the hodlers. Well, we all know what happened and why this hurts a lot now.

Had 300k DOGE and sold them in January 2021 for a 200 $ profit. This was really not foreseeable I guess, but it still hurts. That would have been a once in a life opportunity, but somehow I sold before the mooning of the century because I didn’t think DOGE will go anywhere and just had it because it was so easy to mine.

Sent an ERC20 coin worth about 600 $ in 2016 to a coinbase ETH wallet where it‘s stuck until today, it‘s now worth x100. This one really hurts the most, because I actually see the tokens on Etherscan, but since it‘s a coinbase adress and I don‘t have the secret key, I can‘t move it. Coinbase says they are technically not able to help me, even if they wanted to.

Hurts to think about, but well I think we all made mistakes and as long as you learn something, it’s ok.

So I want to hear, what are your worst crypto mistakes?
