Day trading is a skill, so practicing should make you good at it right but it is good only when the whole market remain in under-prediction because when market move unpredictable from effecting any news than in one day you have a thread of losing your money so be aware to work daily trading,
The crypto market is unpredictable. As whenever some news gets published prices go crazy up or down.
This is the reason why you use stop losses!! I see so many traders who think stop losses aren't that much useful. They are more afraid to get stopped out when they use one than losing their whole balance. This makes no sense at all.
Successful day trading needs a lot of time, focus and patience. Some guys can learn it in a few months to be profitable. Others need years to reach that level.
My advice. Don't look how good and quick others can learn it. Find your own pace, where you are comfortable with. And try to find your own style, instead of blindly copying other traders. If you hang in, you will see that at a certain suddenly it all makes sense and you get it. Then you know you're on the right path.
