The Whales, bitcoin holders who manage between 1,000 and 10,000 Bitcoins, who had sold when the price had topped $30,000, have changed their strategy and are now accumulating.
Not sure what research has been done to reach this conclusion and we have to assume that the so called whales are either using one wallet to yet again to accumulate the coins to monitor these investment, if not an exchange has to release these details because they have complete control over their customers, so i would like to know about the research to reach these conclusion.
