Bitcoin can begin folding in the expanded contract features performance enhancements that are the hallmarks of Ethereum, Ripple and other specialized blockchain inventions.

Exchanges are calculated on BTC but the value back in USD, so when BTC increase the price of other currencies tend to decrease accordingly.

The same thing happens when traders think BTC price will fall they will trade in Altcoins resulting price increase.
