I think if bitcoin rose quite steadily and slowly people wouldn't look at the best cryptocurrency with an "evil eye". Going forward, do you think a slow steady rise, rather than a speedy erratic rise is good for bitcoin to get "accepted" all over the world? The sudden rise seems to scare people and governments.
That rise from $7000 to $20000 did more loss to bitcoins than profit. Most of the big investors withdrew their investment for higher profits at that level and thus prices crashed.
