Bitcoin and all the information I could find about it in the last years taught me everything fiat-world couldn't.
Most important takeaway for me was: Time preference is the key.
I have been poor and stressed all my life and now I am able to think about my life relaxed and not hounded.
Thank you Bitcoin, Bitcoin authors and creative Bitcoiners!
I've always been cheap as an adult. Poverty kind of forced me into it and my parents credit and financial failures made me afraid of credit (I got my first credit card at 30).
When I was growing up though I was super high time preference. Always had to have the latest Jordan's etc.
