I think our emotion makes us a good trader too because if we have control of the emotion, some moves that we see with candlestick spikes won't scare us to exit the market

Emotion too breeds patience. For us to be a good trader, we need to be super patient.
That's right, a trader whose emotions or ambitions are high will usually make him lose. A trader must be good at controlling emotions, don't act rashly. First, investigate the coin you want to trade, whether it's technical or fundamental.
