This is usually not the case. Now it has entered the strongest economic cycle. In 2019, the cryptocurrency market will also change dramatically. Many coins will be born. I believe Bitcoin will develop very well in 2019.
If not then some of us ask same question in 2019 - what if Nothing Change in 2020?- 
2018 is not a profitable year for almost all Crypto enthusiasts. Though there's an increase in adoption of blockchain technology but almost all crypto assets have lost close to 90% of their all time high and there seems to be no light at the end of the tunnel. In some weeks now, we will say goodbye to 2018 and the hope of market recovery will now cling to 2019. Though am not trying to be pessimistic but what if nothing change in 2019, what if the bear market continues unabated, will it be the end or sign of the end for Cryptocurrency because I don't think many will still continue to retain their hope if nothing positive happens at least for the first quarter of 2019.
this 2018 is not profitable year. And 2019 can not be a profitable year for us hodlers too.
