altcoins do not follow the bitcoin rally, you should know that, yes even though there are altcoins that follow bitcoin,
but almost all altcoins when the price of Bitcoin goes up altcoins will experience sideways and even dumps,
don't choose altcoins carelessly if you don't want your portfolio to decrease
In the second half of 2017, when Bitcoin began to rise sharply in price, almost all altcoins also experienced strong growth. The next year, when the price of bitcoin dropped 70 percent, altcoins fell in price by 90 to 95 percent. Now the growth of altcoins after bitcoin is observed, however, altcoins are growing in price very slowly. Moreover, some show relatively good growth, others are very weak, and still others even practically stand still or even fall a little. Probably, it should be so. Everything should depend on the prospects of our coins and tokens.
Back in 2017 that was fomo and panic traders begun buying every atlcoin that has potential to grow and some have fallen into scam ICO, altcoin market is tricky right now you might lose a lot if your not careful but you can profit from the price volatility but i`ll leave that to the expert.
