Every time bitcoin price goes up,Altcoin price take a dip.
This is not allway the case, market is not so simple. Sometimes traders sell off altcoins to purchase Bitcoin, that is why dip is created.
However it is usually temporary situation. In general, stronger Bitcoin = stronger altcoins
No doubt bitcoin rule the crypto world and sooner or later it will become mainstream.
Once it happens, btc will be worth million dollar.Will then all Altcoin be died?Seems Altcoin price are inversely proportional to btc price, if btc keep rising, will Altcoin keep falling? .
There always be some new altcoins created, because either: developers want to create something new and unique or they want to grab your money by creating another pump and dump altcoin.

Dollar will eventually kill itself. Just wait and see.
