Hi guys, I'm confused so I'm asking you about it, because this community has been really useful to me. I've started trading a month ago. Following the markets, applying the moto "Buy low, sell high" and hodling when I needed too. Compared to a good friend of mine who did all the newbie mistakes and lost 10% of his investment so far (selling when it drops, buying at ATH, trying to do technical analysis), I thought I was doing pretty well: getting to know the coins I was investing, buying them at the dips when I thought the price was low enough, selling them when it seemed too high. In a month, my portfolio, when considered in FIAT currencies, went up 20%. Recently, the alts pumped very much, so I sold most of them, for ETH and mostly BTC (using Bittrex). Problem is, ETH and BTC are down, 8 and 5% in my portfolio, canceling most of my gains. That sucks. I mathematically understand why it is so, but I guess the mix of crypto confuses me. What should have I done...
