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
Bitcoin price movements affect altcoin prices and I think this is reasonable because the cryptocurrency market is Bitcoin. Altcoin which has a large market cap value will also be affected by Bitcoin but in my opinion it has an opportunity to grow
