but its better not quit since the long term trading can be helpful and with just stable coin pairs they can make decent returns with minimal risk from my knowledge.
But at some point it's good to take a break off trading if you observe your strategy is not producing results anymore, to learn and advance on your trading skill instead of struggling with a old strategy that never works, because as time goes by so is the market pattern changing with respect to several factors, which could include government policies, the world economy and e.t.c.
A concept so many traders never gets to understand and that's how complicated trading could be. Just like the highly volatile market, so does the strategies change to suit its volatile condition.
I might say trading isn't meant for everyone. Because your into crypto doesn't mean you must trade. You can hold and still get to have some good results off your holdings rather than trade it away in search for quick profit. Quick is always dangerous and your always at risk of loosing all quickly too.
When a trading strategy isn't working out an expected result or as usual, you might have to pause, observe for what is changed in the market and come up with something new.
