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.
Yes and with the cancellation of segwit2x, we can see that the price of altcoins are now starting to recover and bitcoin's price starting to dump. People are dumping bitcoins now and are starting to invest in altcoins. This is why we see the sudden change in altcoins prices. But I think it is just a matter of time before bitcoin's price recovers back again and reach a new ATH.
