trading advise needed

I'm new in crypto trading since a couple of months ago so I need some advise for it.

I made the in one of my first days 150% profit but due the lack of trading experience I mist a huge amount of profit, I'm talking about 400% .

So can you guys give me some advise in how to make more profit without overtrading and what' s the best way to learn technicals analysis?

thanks a lot!!
