You could try this instead: Be sure to keep reading crypto news and price analyses — not just staring at charts. Even though you shouldn’t give in to the FOMO and FUD generated by many crypto articles, you still need the news in order to stay apprised of market conditions. Also consider setting stop-loss orders to ensure that your losses will be mitigated in the event of something like contagion.
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.
