Some good observations here but I'm not sure the exchange issue is the reason Hive dropped in value in July. Virtually all of the alts took a significant hit at that time.
However, what does seem irregular this time in the cycle is the Bitcoin to alt coin price ratio, it seems a bit out to me. Let's not forget BTC has been trading not that far from its ATH pretty firmly for the past few months, yet the alts have taken a huge hit. I'm not sure it was the same type of BTC to alt coin price ratio this time in 2020.
I don't know if @edicted has any thoughts on this?
