Why Crypto is an  Route to the Longest Bear Market in History ??

in 2018 jan 28  the bitcoin price run was 500k+ $  increase. in 2019 it was much smaller at 3434$ only but still very much a run. 2019  also had.  also note at the lowest point in the last bear market bitcoin never even got close to where 2019  started before the run up. the market low was found in spring of 2015 around $220 or 5x lowest than the start of 2013 however it was an 80% peak to trough. 
if history repeats 2018 will not rally, it will simply be a consolidation year. weak hands will be shook out. difficulty may even fall on many alt coins. maybe even bitcoin. we may have seen the low at 3k $  and we may even test . . i'm sure a lot of miners would shut down. network traffic would fall. 80-90% of altcoins would die.
