Lots of traders use bots (you might want to as well if you have the chops). To the next point, lots of traders use trading bots. Some are white hat; some will try to get you to make bad trades. Keep an eye out for bots. If you are using a bot, be careful, there are bots designed to exploit poorly programmed bots. In general, if you don’t have a solid grasp of TA and crypto trading, skip the bot. They are only as useful as the strategies they run.
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.
