Altocoin investment is not just up and up with all profit. Down price must also be factor into your objective so as long as you see your coin going red you don't panic. There isnt any coin that don't go down.
Every crypo coin has ups and downs but that's not at all the problem with the experienced users and early adopters as they are well aware of the situation and market fluctuations but the newbie to crypto invests mostly into altcoin without checking prospect and then end up doing panic sell when the value goes down.
