Does money grow in a crypto wallet?

Excuse me, I am quite new to the world of cryptocurrencies. I've heard a lot about crypto wallets and how they store digital assets, but I'm still a bit confused about one thing. Does money actually "grow" in a crypto wallet? I mean, do the funds increase over time, like interest or dividends might do in a traditional bank account? Or is it just a place to securely store my coins without any growth potential? I'm trying to wrap my head around this concept and would appreciate any clarification you can provide. Thank you!
