Pandemic, and other problems in between and now we have these storms closing to our country. What a year, anyway I think that could also be because of the things happening and people are quite attracted to Bitcoin, with a lot of people going in and going out I guess that makes Bitcoin more unpredictable, something we can get from this chart, I guess.
You could say that about every year in this case. Remember 2017? Bitcoin was supposed to be in a downward spiral with all the internal wars going on with big blockers. Ethereum was supposed to do the Flippening and CryptoKitties would push it to the top.
But Bitcoin improved and ETH went down.
And trade wars in 2019? Made Bitcoin go even stronger.
Every year is difficult to analyze, and hundreds of experts get it wrong every day;)
However let's be realistic, we are getting closer to almost 1 year of pandemic and people trying to stay at home as much as possible and wearing masks as much as possible when they go out which is like the middle ages with masks of big nose thingies.
So, yes every year had something but for the past 70 years or so since world war 2, there hasn't been anything that affected the whole world at this scale, this year is much much different than the other ones.
