Exactly how I look at it, tuition. In a bull market a lot of holes in your game/understanding of markets is washed over by the exponential price action. It is easy to feel like a genius, at some point we all get exposed by either taking too much risk or lack of knowledge. I am thankful I was able to learn those lessons when I did and not later down the line. After that loss it made me semi obsessed with understanding and learning about the pieces I was missing, market cycles and global macro. Sounds like you have had some similar experiences and are on the same path. Always keep learning and adjusting.
I am annoyed but learning nonstop.
A emergency fund that's 110% liquid is necessary especially today. The ROI is trash but it serves as a purpose.
LTC was annoying. ADA has replaced that annoyance over the years. While up on both I no longer accumulate once a position stalls out. Similar to sports betting, I look for lopsided betting odds not getting it right. Annoyed if I had thrown ADA bag all on Sol, mana, enj etc but... it is what it is.
The play I think now is loading up on btc on the dip when ALTs run. I am still trying to learn more and find resources but. Curious what resources and info you follow? I watch twitter. Few YouTube channels. I want to jump on mastermind groups.
