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.
Since investors are seeing Bitcoin as the most stable cryptocurrency, theres nothing left for most of these altcoins than to be stable. Most of the time when the altcoin market is falling, investors quickly withdraw their and send it over to Bitcoin and such action thats being taken by most of these investors causes altcoins to be highly volatile.
Someone once said that whenever altcoins increase in price, they increase more than Bitcoin, and when they fall their fall is worse than Bitcoin, because they fall to the extent you will see more loss. And since Bitcoin is considered by most of the investors, it is seen as the main cryptocurrency. New investors mainly go for Bitcoin and not altcoins.
