What's the best Crypto Investment advice someone has told you except: DYOR, HODL & DCA?

I got my first investment advice from the same dude who taught me all about Crypto: "Don't do futures unless you have a setup" and "don't regret trades you've already made"

Naturally I was curious to try it out and I lost some money in it, but I learned my lesson and I'm glad I did it before I put any serious money in it.

So what's your best advice someone has told you or you learned it yourself except HODL, DCA and DYOR cuz I think most people in this sub already know this.
