What do you mean by Altcoin Season I dont think theres such a thing because what I believe is all currency in crypto are independent so each will grow or fall by demand and not for what ever reason
The developer and marketings team will be the responsible about their currency performances so if this one will grow or that one will dump its them to be blame or praise
But what we have to do?choose the right one before investing and stop trusting shitcoins that will bring you instant profit
