The relationship between Bitcoin and Altcoins is very close, Bitcoin usually rises in price and altcoins do as well. Conversely, Bitcoin decreases altcoins, but some Altcoins have positive news from developers that cause them to increase in price when Bitcoin falls in price.

The relationship of altcoin and bitcoin will be there when the bitcoin pumpers are feeliing boring with bitcoin markets and they will start to pump the altcoins. When there's a good news for altcoin and those whales will be moving to the altcoins and create pumps.
