What will happen, when the altcoin season is over?
I have seen many coins that are up in price x20 x50 x100
Like pivx, decred,stratis and many more. Will they dump again?
And when will this altseason take end?
Nope.
All of them have their own improvements and innovation, even if we dont use them as a currency. Just look at ETH. Big companies use and develop various system based on that. Keep this in mind.
