Investing in bitcoin does not always mean that people have now moved to the side of decentralization. A great many bitcoin investors store their bitcoins in centralized services or custodial wallets. It's definitely not about decentralization, although their asset allows them to opt out of a third party. So far, centralization has very much dominated the crypto market, and that trend will only intensify over time. It would seem that over time people should learn to understand the full meaning of cryptocurrencies and bitcoin, but something is not going according to plan, and people are choosing convenience over decentralization and self-custody.
