I'm quite a beginner in crypto and I have about one week of trading.
I find trading quite easy, I managed to learn from my mistakes and observed different market patterns.
My current performance (average) of
daily profit is around 1-2% and I have no clue how far I'm from those who are expert traders

I created a poll if you don't want to share your experience, in case you suggest new options, please let me know.
I have also a strange feeling that these earnings are done too easy comparing with other offline jobs and I don't see it quite fair

1 to 5% daily is not a bad one, you can be making good amount of money with this percentage. Although I don’t think that trading is as easy as you have stated in your last paragraph, I have still seen people who are struggling with it despite that they have learnt all that they are meant to learn, but they still can’t find a way to make good profit, while there are those who are making profit to the extent they have decided that trading will become their day job and they even go ahead to quit their jobs from offices.
To achieve something you have got to commit time, hard work and lots of money, if not it’s going to be a waste. So, if you’re able to be getting 1% or 2%, that’s good, in a month you round up with 30% to 60%.
