I think the cryptocurrency market follows market cycle patterns similar to stock and other markets.
For example, we can see a similar chart every few years for Bitcoin... This one is for 2013-2014.
You can read more about market cycles in Wikipedia: https://en.wikipedia.org/wiki/Stock_market_cycles
"Cyclical cycles generally last 4 years, with bull and bear market phases lasting 1–3 years".
I guess it is too soon to expect the bull market yet (whether we want it or not).
