According to the motto: If you don't think, you're out. When large companies buy up large amounts of Bitcoin, some say that it is good for Bitcoin because it causes the price to move up. In my opinion, however, it cannot be reconciled with the basic idea of Satoshi Nakamoto, which says that everyone should have the opportunity to participate in the infrastructure of this currency. Do your own research and make up your own mind. Always remember: Not your keys, not your coins.
