I think bitcoin is forming a head and shoulder pattern which may lead its price to 38k-39k region and after that bull run will start, most probably after 18th oct. It will be the best time to buy your alts on a discounted price, so def. go for it. fear and greed index on that price will be below 20. But what if, btc do not respect h&s pattern. keep your eyes on 43.5k-44.5k level it may come back harder this time. i will be bullish if btc crosses 45.2k but before that buy your alts in all this FUD.
