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?
Don't ever ride a hype coin and especially at the peak of it's pump. Always do your own research and avoid trolls that says this coin or that coin is going to the moon.
