Even altcoin like ethereum that solves real world problems still have its price heavily influenced by bitcoin's price due to problem you stated and since bitcoin is like the "currency" of the cryptocurrency market while other altcoin are like it's operating system.
Not all altcoins depend on bitcoins because there are times the price jumps up and some alts follow the trait so its difficult to determine factors that affect them but ”CONFIDENCE” in an altcoin is a good price booster.
I guess most altcoin holders are speculators, out to make a quick buck and when they feel the bitcoin boat get rocked they jump ship.
Well said bro. But the issue is what happens when u are about to get real value for the altcoin that is not affected by bitcoin's movement? You convert to bitcoin right?
Bitcoin as base currency really sucks for altcoin holders.
Now you got my message haha!😄
