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?
It won't destroy altcoins. The bleeding that we are seeing in altcoin is due to the fact the altcoin traders are going into bitcoin scene because of the anticipation of segwit2x which they can get free money out of it. But once the looming fork is completed, there no way that they will stay on bitcoin. They will of course goes back to altcoin and the market will see all green again. So bitcoin won't kill altcoin, this is just a temporary hiccups for the altcoin ecosystem.
