from my experience, trading indicator doesnt work well in crypto. i test many time and often fail with those indicator
i believe in price action which can work better than indicator. furthermore, price action is simpler than indicator
It has been known for a very long time that if you try to use trading indicators in markets that have very low volume then they don't work, but if you use those very same indicators in markets with enough volume then you will get very accurate results with them.
But you found the right answer, when you cannot use trading indicators and fundamental analysis is useless because of the huge number of scams your only option is to watch the price action.
