The fact that txn are super slow and the fees are huge is scaring the people too, they prefer to sell regardless of what happened in the past. Although many of the sellers are not trying to GTFO but thought btc reached a nice pricing point and are cashing to reinvest
that is not the reason why people freak out and start to panic sell. the main reason why bitcoin drops is because it has still undergone on a correction. the other factors that i think is because we are now close to christmas day therfor people are expected to withdraw and cashout their bitcoins to be able to prepare for this season like buying gifts and buying grocies. lastly coinbase has now approve and hold bitcoincash in addition to thier wallet support, this can be another reason on why bitcoin had decrease.
