Since the creation of bitcoin and other altcoins the cryptocurrency markets have been very volatile, not just this year. I mean, take a look at 2017-2018 alone.
that year should be a bull market?
Supposedly as 2018 dump hard but it seems 2019 got even more dump. Altcoins are just following the trend of bitcoin while the worst part is that it even dump more. However, the 3rd and 4th quarter of 2017 is definitely a bull run for mostly of the top cryptos.
Hopefully, halving could bring us prosperous 2020.
