Now a days all alt coin markets has been dumping and dumping without any simple pump for the btc price increasing.So just i want to know that can bitcoin destroy the maximum type of alt coins market?
I dont really sure that bitcoin can destroy the altcoins market because altcoins was born because of bitcoins, even if most of the altcoins price decreased because people dumping the coins there are still some coins that growth exponentially some that have unique and different project and development than bitcoins

To have a healthy market altcoins is a must. Though majority of the altcoins were small in value compared to bitcoin, it gives a competence. Such a healthy competence is a must paving path towards growth. Upon such a thinking bitcoin will never intend to kill altcoins.
