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

Not bad, and actually to say you that you are lucky to have that profit every day while the others are struggles to earn a few sats in trading. You are already on the right track, you can improve that in the future if you will keep that strategy.
If you are adding more into your capital, expect your profit to grow because that also a factor. Big capital, big gains but it also has a huge risk. But for you that have already the system used and have an effective strategy, it is no longer be a problem. You only need to stay on track and avoid too much greed.
