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?
Very simple the principle in trading, you will just buy at low and you'll sell at high. It's not that hard to understand mate but I guess you think yourself wealthy enough to buy at peak. I suggest to you that always check and monitor the prices of alt coin and learn it by yourself. Try to read some insights from the experts.
If it would be that easy, we all would be rich. But patience is a good partner for trading with altcoins. When you look for example at price of ETH, XEM, RIPPLE, DOGE, BCN, LTC a few months ago, you see, that nearly all of these currencies climbed up multiple times. I sold doge at a price of 0.00032 $, because I thaught, that price was its high, instead of holding them just a few weeks.
