Many people say that the prices of the alternate cryptocurrencies are reducing because of the reduction of BTC prices. Bitcoin is know as the first crypto currency but other alternative currencies such as Eth, Ripple, Lite works as individual platforms. Therefore how the other crypto currencies depend on BTCs?
Simply because they are made after bitcoin. Bitcoin is the blue print while other crypto currencies are just an carbon copy. Bitcoin is the origin of all currency and without bitcoin then there would be no currency at all.
