lol there is no altcoin season but it is the Bullrun that who's been waiting and that is about Bitcoin getting higher value so altcoin can do follow the movements but the altcoin itself?there is no such thing .
just like what the links says,Bitcoin Bull willl be the start of altcoin season as well
Why do you think the BTC will move alone? The correlation between Bitcoin and altcoins shouldn't be ignored and it has proven there is a strong correlation among the top altcoins. The main reason everyone thinks the Bitcoin Bullrun will bring the alt season is the past market tendency. The market will repeat it's trading patterns one more time. Everyone is expecting a different and thinks it will not repeat this time but it repeats seasons, surprisingly.
