2017 yesterday was a good year on cryptocurrency, many people speculated and also reviewed with a variety of data that in 2019 the return of the era of cryptocurrency gold but in my opinion it will happen in 2020.
2020 is scheduled for Bitcoin Halving day, so we all know that we will experience something very different according to the cycle. But I am sure this will also have an impact on the authorities who will complicate things, especially ico and exchange.
2019 is a trigger in determining potential prices next year, if at present it seems to be increasing, in the future many speculators can analyze prices to be more optimal.
