most of those "speculations" are not speculations, they are "wishes" with their authors calling them "speculation"
i remember back in 2017, in fact it was exactly 1 year ago today in January 2017 when price went to $1100+ the same drop happened and the same "speculations" were saying "it is a bubble, China bans bitcoin, it will drop to $600 and then $6000".
the drop was to $930.
i wouldn't put too much faith in any of these speculations. the market is now testing new buy supports and there was no reason to break $10k and go below it anyways! but i would love some cheaper coins in my paper wallets.
