For more experienced traders (or at least some experience) there. Which would be the minimum to invest in order to have a chance to profit from trading? I would like to start as low has 10k satoshis, but as I have seen, many exchanges have minimums and minimums fees and that does not feel reasonable.

Let's say that we put a goal to earn 20k satoshis a day (on average) from trading... How much would you see you have to employ to achieve that?
