I will never be able to calm down if the coin price at the exchange place falls because it can make me lose a lot and lose the assets that I have. I better secure assets by selling them even at low prices.
I always calm when the market is red because it is the best oppurtunity for me to buy more coins that i will hold for long term, and when the market is falling i am not worrying because it will recover again, but off course it will take long time before all the price of coins will be high again.
