The title of this thread immediately made me think of this:
https://www.youtube.com/watch?v=tzW2ybYFboQI think the next bubble will top about $2500 or more, so I won't do anything at $1000. At next bubble top (which I'll try to pinpoint) I'll sell about 10-25% of my holdings.
I doubt it will go to anywhere near 2500 anytime soon, though I think 1k is doable again but probably not before the next halvening.
