I mean they are interested in Bitcoin since early 2017s, they say bad things in public and buy Bitcoin in private while keeping it secret.
Whales when they are planing their games, they will not announce their games are setting up. They do it secretly and during the same period, they make us fearful. They will make us panic to sell coins at corrections, collapses and they accumulate cheap coins.
So there is no way you get to know that they have already bought what they always opposed.
We never knows about details, who play the games, who are Bitcoin holders but with on-chain data and analysis, we can see whales' on-chain traces.
So once they are done buying, they start sharing news in the market that they are thinking to buy so that the price goes up and they can dump it on you. Institutions are here to make money, not build technology. Only individuals can build products.
They can do both, building products, setting up market games, and gaining profits but most of institutional investors simply investing and manipulating the market.
