Hi friends:
What is the reason for the large fluctuations of altcoins in your view? Why are altcoins so fragile compared to Bitcoin and fluctuating with the smallest news? Of course, I mean the altcoins that have good ideas, professional support,... not the shitcoins.
In my personal opinion, altcoin is like relying on bitcoin, I even saw a few times when bitcoin prices began to fall, then most altcoins also went down, and vice versa, so I concluded that good altcoin is like there is a dependency on bitcoin.
It's because if there is a downtrend many of the exchanges doesn't support direct conversion of Alts to fiat or stable coin. Even if there is a market its volume is very less so people tend to sell the alts towards BTC to convert it to fiat or stable coin this leads to the fall if BTC tends to fall.
Another reason would be if BTC falls or the cause of that fall will also be negative for the entire crypto industry so it might also be the reason for that. If the dominance of the BTC decreases then at that time alts soar against the BTC
