About 5 years ago the price went down from $1000 to $250, see where it is today. So what? As you can see it's not because the Bitcoin price goes down to 70% that it means the party is over. Bitcoin started to be mainstream only 2 or 3 years back maybe and the project is 10 years old. So give it time and have patience
I think you're right. Op has made a point that whales are slowly selling off but I don't think bitcoin has reached its mainstream potential quite yet. We will have to wait and see...
