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?
Sorry to say but this doesn't mean that you are brave if you buy altcoins at high price in fact it is somehow a stupidity to rely this much on altcoins. According to me till now bitcoin is the only cryptocurrency which is reliable. Altcoins trading is more risky than bitcoin, i will never suggest you to invest a big amount in altcoins. There isn't a big strategy behind the altcoin trading, just concentration over the market before and after picking one of the emerging altcoins to invest in.
