what do you think about altcoin,do you think is the time to buy? am afraid because all my money is heading to zero..

Don't worry about altcoin is going to dump hodl your altcoin until the price is rise. I think you should better to buy altcoin because the price will rise up again.
Yes, as you can see, many altcoins are recovering everyday with a pump speed of 10% to 40%, so I do not think all altcoins are dying, some are dying only. It is better to buy and hold coins already listed on big exchanges.
