Remember those candlestick charts we see on every exchange? By studying them, we can find indicators, and understanding what these indicators mean can help us better predict the future price of the chart. There are tons of indicators and they can take some practice to become adept at identifying. You may find it easier to focus on practicing to identify them one by one until you become comfortable with them, slowly building your repertoire until you feel you’re ready to go full boar with your trading career.
Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.
