One of the preliminary lessons I took from a crypto expert before I joined crypto was not to trade or invest with emotions because crypto is dynamic and can make sudden change in trend at any point in time. The lessons was furthered with the essence of performing extensive personal research into projects or coins before choosing to invest in them and once this happens, the significance of patiently holding till it rises when bear markets set in.
Yes! our emotion has a big effect on us because it can really affect our decision just like when the price of bitcoin rise we can decision whether we convert it in our national currency or kept it because of more higher possible increase of price of it same as if the price of bitcoin is low it has a possible to hold the bitcoin and wait it until it get high again or just get it.
