I personally think that I don't. I trade here and there and not that much so I could be considered a "mid-term investor" instead of trader but if we consider them about the same then I can clearly say that I don't know when to buy. Most of the time whenever I buy something same thing happens, it goes down a bit, it stays there for a long time, then it goes up a lot.

So yeah, I do profit from my trades almost all the time which means "I know how to trade" but considering I could have bought lower since it dropped after I bought I have technically lost on my profit which is why I think I don't know how to trade. If it comes to day trading and buying/selling with small movements then I am not good at all, I can't know any coin going any direction in that much short span of time.
