Perhaps its another coincidence?

Regardless though, the price of BTC is still within the $50,000 range, perhaps this news didn't really put a dent on the price.

And that is what important for me  I don't know what's OP's Problem or Main concern if there is transacting either deposit or Withdrawals a almost 15k bitcoin when the truth is market is now in peak so decisions may come often for those Whales inside crypto .There are some who bagging Money and some that wants to bag money in future.
No matter what reason is ? for me it is the 50k level that concerns me more .
