Volatility is pretty high on exotic pairs which increases the risk of trading. Because of this huge uncertainty factor traders avoid these pairs.
I believe beginners should start trading on higher timeframe and familiarize themselves with price action strategy. Apart from this, they should also focus on learning risk management and emotional management.
