Perhaps because many people (investors) were disappointed with ICO scam, negative perceptions of Crypto were excessive so there were many positive conditions, but it did not affect bitcoin to create bullish.
in my opinion 2013 is the rise of bitcoins like 2017 and 2018 is a year of bad luck for bitcoin and I think 2019 is a year like 2013 hopefully just like that from me thank you
2013 is like we get a big profit, it cannot be denied if 2013 is our glory, while now 2018 is our fate, we are usually hoping that prices will hopefully be stable and rise dramatically.
