I have recently been into altcoin trading. I just want to know, does the price of bitcoin affect the price of other cryptocurrencies as well? How? I really want to know. I have noticed that ever since the bitcoin price pumped up and reached 4,000 USD, the price of the altcoins had gone really really low. I almost lost my invesment due to this sudden drop. Does bitcoin price have something to do with this?
if I think btc affects the price of altcoins that are popular and owned by many people, if for altcoins that have just been released and especially less popular coins I think the price of btc only has little or no effect, because enthusiasts on popular coins will remain small if btc prices go up so people will prefer to invest in btc than in the altcoin, so I think

Bitcoin is the first cryptocurrency. When people understood that the other guys are ready to invest in it, they started to create various altcoins. We can say, BTC helped to create the crypto market.
