Don’t zoom in too much on the price trends of the moment; don’t sweat the small things. It’s easy to zoom in and get stressed when Litecoin goes from $220 to $213 (or something like that). However, these little movements only matter if you are day trading large amounts of coin relative to your total investable funds. Zoom out a bit and look at trends over larger periods of time. Don’t think of that $213 relative only to $220, think of it relative to the $100 Litecoin was at a few months back, the $400 it was at after that, and the $100 it was at just a little while ago. From that perspective, a fluctuation between $220 and $213 is nearly insignificant. I will rarely make trades on timeframes shorter than 2hr candles, and I generally am looking at 6 hr and 1 day candles, because I value my sanity and am focused on the long term trajectory of crypto. That only changes in very specific instances and with purpose. If you zoom in too much, you lose sight of overarching trends (many of which are actually stronger indicators of what is actually happening).
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.
