Altcoins are not dying it affects the price of btc thats why in all tradin site all coins are going red and dumping ..As my observstion here in crpto world .. Bitcoin's price and altcoins price have alternate move when the btc's price up the altcoins down ,vise-versa. Dont lose hope it is the best time to buy altcoins 
) and wait it to pump ..last condolence to those altcoin holders dont give up its only a challenge and congrats to all btc holders .
Most of the time the effect of bitcoin price growth is in favour of altcoin they grow with the growth of bitcoin price but sometimes when we see insane kinda growth in bitcoin price the alts can't hold their price because people withdraw their money from altcoin to bitcoin. Right now the effect seen on the alternate market is due to this reason. ) and wait it to pump ..last condolence to those altcoin holders dont give up its only a challenge and congrats to all btc holders .Still we have some powerful alts whose price is growing very well like cardano, STRAT, QTUM and Waves price growth is pretty impressive.
