not only you, I also suffered a lot of losses, I hold several altcoins, used to be worth more than $ 5,000, now the price is broken, my altcoin value is $ 200 
indeed most altcoins will become "junk coins"
Your altcoin value dropped because all people know it's because bitcoin price. If you are lucky, just wait until the price (expecially bitcoin) back to the track and your altcoin value will be higher than now. indeed most altcoins will become "junk coins"
