In your experience, apart from the large growth in 2017/2018, what was the largest spread during one day that you have witnessed so far?
I joined early 2017 so I witnessed the growth of bitcoin. There's where times that bitcoin will go $1K swings daily, it was fun to watch the market grows significantly and everyone was very happy. I'm not sure about prior years though, there might be large spread specially after the bearish trend of 2013/2014, but I may be wrong. Perhaps early adopters or some Legendary accounts can chime in their experienced prior to the bubble we witnessed in 2017.
it was a pleasant sight, I felt that and everyone involved was cheerful. unfortunately this year we were given a very big test.
but at least it's still grateful that bitcoin still has a price, and we can still buy some altcoins for big trade.
