I do believe that history repeats itself more often than we think in a cyclical way. The way to visualize these cycles are the graphs that are analyzed with the tools of technical analysis.

2018 chart looks like we are following the 2014 roadmap for a long-term bear market. Like 2015, the crypto market will spend most of 2019 building a base around $5,000 or $4,000.
 
If the graph is fractal, at the end of 2019, the market will begin to grow and continue its growth throughout 2020 to explode upwards in 2021.
