I have a feeling we will never see an altcoin season like before. There will be an altcoin season but its going to pale in comparison to the last one and be more centralized around a few core altcoins such as litecoin, ethereum, doge, eos (maybe steem lol) etc.
There are more laws, regulations etc this time around that where unknowns last altcoin season where people felt like it was free money for all!
