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 think it does not matter if you are too brave to buy Altcoin for a high price, provided you have enough BTC to back up the possibility of the Altcoin price you bought is down.
