Personally I don't understand the thesis of acknowledging the price can drop 25%+ to $6k area but not 50%+ to $4k level if there is natural bearish correction.
you don't understand it because you are calling it a "correction" and your percentages are way off the mark.
a drop down to $4k is not only not a correction but also it is a gigantic crash. the size of it is going to be a little less than 70%. so in other words if you even consider $4k you are considering the market to crash (for no reason i should add) hard!
