The simple answer is when there would be a bitcoin season, there would come an altcoin season. The answer to would the altcoin season ever come, the answer would be yes. But the most difficult question to answer is when? Bitcoin and altcoin season would come that is a certainty but with increased uncertainty in global economics not just the tariffs or trade war but also our decreasing population and limited and slowing demand of goods and services which would soon go towards diminishing side and how our economy develops in such negative growth period. I'm still hopeful for altcoins and accumulating it in hope of good ROI in future.
