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?
I don't suggest that sell it. you can wait some time for pump. other If you guess that market can be over down you sell it and wait for again buy.
