What is the “safest” cryptocurrency?

Hi, I'm new to all this crypto stuff, I dont know jack shit lmao

Right now Im just lookiin for a place to deposit my money or part of it.

By safest I mean that It maintains its value consistently, im not concerned of how much it raises value as im concerned about how much it DOESNT lose its value in a long term, and if it does, minimal if possible

Also I would like to know what wallet/app do yall guys recommend to use for this purpose

Also what physical crypto wallet do yall recommend me to use?

Any other advice or tips u can give me are more than welcome, just be honest and kind, Im a beginner after all
