It is great idea to monitor the the whales movements, but the problem is if you make it public the whales will know it as well and
can trick us out and confuse with moving their coins around.
I am also following and analyzing the movements for some specific ICOs but it is time consuming and I would like if there would be a tool to get the information easier.
One way to fix the issue you are talking about is for him to implement cross-chain analysis to detect such movement.
