I will start hating altcoins only when bitcoin raise up to 20,000$ and altcoins fail to move up as well, many people are putting blames on altcoins today as if bitcoin is not in loss itself, the ATH of btc was 20k and now it's trading for 7,000+ thats like 12,000$ lost please how will this not affect other altcoins as well? Top altcoins will surely lose value as well, to me this present loss of altcoins are positive, look at coins like LTC, EOS, BNB, these coins are doing fine. You will only have problem if you invest in crap altcoins
If BTC raises up, expect that altcoins follow so there is no use hating altcoins in my POV. Both have different purposes in the crypto world so you can't dismiss altcoins but I do agree that you will only have a problem if you invest in altcoins that you don't know. You should do your own research before investing as others do. I know most of the investors don't trust some altcoins anymore probably because a lot of ICOs have gone wrong in the early years. The competition in altcoins is fierce so I guess only those who are able to keep up stays in the game.
