I can assume that it can affect the trade in some way ,
can look for changes in this amount of BTC in the order book but is this info can tell me somehow if the intention of the whale is to pull up or down the market ?
How reliable this type of data can be ?
Same scenario can be of leaving the exchange..
Over the time, I guess we cannot identify and follow whales as they may hide behind multiple small amounted transactions hence now itself we should start practicing a trading habits without following them. Anticipating the future changes and enhancing ourselves based on future demands will definitely help us to stay competitive.
