CZ also includes the Binance LABS investment fund. This fund sponsors many different crypto projects. My personal opinion is that CZ is actively supporting the crypto market while creating an ecosystem. Everyone finds it convenient to join CZ's ecosystem. It also gives a solid flow of money in the crypto market.
The decentralization in the crypto market has gradually disappeared as the involvement of investment funds in recent times has been very large. In addition to Bitcoin, all remaining coins on the market are manipulated and not decentralized.
