If the whales are secretly buying up Bitcoin than I will buy Bitcoin at the current market rate. Even if it goes to 2500$. Gives me sum hope in the crypto space. Only if I find out they are buying through forums etc.
This is not the right guidelines to buy Bitcoin, you just prove yourself that you cannot make your own decision, buy Bitcoin when you have done your own research not because Whales are buying, but because you have found out it's potential in the market.
