The $160 price hit in early 2015 was a real 'oh shit' moment but things had been falling for so long that the tone was seriously muted which is probably the one time I've seen true capitulation. By that point no one cared all that much any more. We got the endless $250s after that.
2015 was an "endless" 200$-250$. Quite a lot of home miners went out of business back then.
For me the "oh shit" moment was when it went to 300$ and higher, and stabilized at around 400-ish levels. I was buying back then. Nothing big, 20$ here, 20$ there.. but it was a "shit, I've missed the train", because I was thinking then that 400$ is too expensive to buy more and I also haven't completed my first Bitcoin.
I haven't seen anything approaching that boredom, indifference and misery this time around. Despite what some feel, it still seems vastly more buoyant. Of course there's not that much point in trying to make a direct comparison as other elements are very different but you'd think there might be similar themes.
It was more like a capitulation for some, not boredom. And it's difficult to compare, because 1200$ is not 20000$ and 250$ is not 6000$. At this level, there are still many people vastly on profit, even here on this forum.
