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
I also think the same as you that at the moment there is nothing wrong with altcoin because altcoin also runs according to its own trends like bitcoin. although now many altcoins are undergoing a bad phase in various cryptocurency markets, but there are still many altcoins that are growing well.
