I do not know so much about altcoins, i do not really invest in so many of them, but i don't think altcoin season has arrived, if i am not wrong, for us to experience an altcoin period, BTC price must be on a quick surge in that period, but none of that is happening, BTC price is not surging fast. Altcoin season would come, but i think those expecting it have a wait a little longer.
