I have experiences of trading with below $10 and making more than 20% of profits.
Are you sure I meant $10 capital and 20% profit? Even $50 would be extremely small capital, imagine $10? market fluctuations Vs exchange rates do not allow it to be possible to trade with $10 unless you make a strategy of buy low and sell high ie buy bitcoin when it drops too much, hodl and sell when bitcoin increases too much, even with that your profit will be low and you will wait a long time for the price to fall a lot or increase a lot. definitely not viable $10
yeah, still you must need good skills.
