The surge in altcoins has led many traders to forecast the dawn of a new altcoin season. According to "The Moon" a pseudonymous Twitter analyst, altcoin seasons follow a major run-up in the price of BTC, especially when the price stalls or pulls back.
Reference
I think the price of altcoins is largely determined by the price of Bitcoin. When the price of Bitcoin goes up, the price of altcoins is also relatively up and vice versa if Bitcoin goes down, the altcoin will also go down. Altcoins are no less good than Bitcoin, some even say that Altcoin's performance is better than Bitcoin even though the price is far apart. So if there is a good opportunity to invest in altcoins or Bicoins, don't miss it, maybe it is your golden opportunity.Reference
