What was your biggest loss in Crypto?

So I just sold around 50 Skill 2 weeks ago for around 1.2 $ per Token. The token belongs to the game Crypto Blades and I didn't really enjoy it so I converted it back to BUSD.

Now 2 weeks later 1 Token is at around 140 $ which means I could have made around 7000 $ instead of my shitty 60 bucks…

Please tell me where you screwed up so I don't feel so bad anymore…

Edit: Thanks to all the replies. I do feel a bit better now hearing some of your stories… I also think that I probably won't ever participate in an ICO or anything similar since so many of you had bad experiences with it
