My mom got mad at me when she discovered that I invested a big part of my savings in Crypto

For a little context, I'm a 21 year old guy that lives with his parents, and over the last three years I've been able to work a min wage job and managed to save most of my salary because they (my parents) insisted I don't need to pay bills. Recently after the big dip I decided it was good time to invest in crypto and put about 40% of my fiat money in.

Fast forward a week or so, I decided to tell my parents about it and my mom got really mad saying that I got scammed and that I'll never see my money back. She also doesn't believe me when I say I can withdraw whenever I want and insists I do it just to prove it to her, but I refused as I would only lose money due to fees.

I'm so mad at her ignorance, and the only reason I want to succeed with my investments now is out of pure spite and to prove her wrong. Thanks for reading up to this point, and I'm sorry if I made any grammar mistakes. English is not my native language.
