My biggest problem in trading is that I was too brave to buy altcoin at a high price, and because of that I often lost my btc, even once I lost 50% of my btc when I bought altcoin at a price far above ICO.
So please give me feedback on this, what should I do?
Emotional control is one of the key factors in Trading, Don't panic and don't get too excited. Pay attention to price movements and what the latest info about the coins you will buy.
Maybe this is a little input from me.
