The point I'm driving at is that exchanges are now taking it upon themselves to foster the widespread adoption of crypto by educating and simplifying crypto and blockchain but this adoption we talk about won't happen overnight.
There is no doubt that crypto exchanges have been a key feature in spreading Bitcoin adoption because people learn about Bitcoin through Bitcoin and crypto exchanges, but some Centralised Exchanges, such as FTX, that collapsed some time ago have reduced the rate of trust people have in crypto exchanges, and as a result, people are not rushing cryptocurrency due to some bad news in previous years.
But as most people are concerned about their privacy and self custody so they use the centralized exchange but most of the new users are still dependent on the centralized exchanges. I also prefer using the DEX but I use to appreciate the contribution of the centralized exchanges in this market and global adoption.
Privacy is the main problem we mostly have with Centralized exchanges because they cannot be fully trusted with our personal details or information, which they demand from the users through KYC. But there is no doubt that centralized exchanges have a great impact on Bitcoin adoption, as many of us know about Bitcoin through the exchanges, and then we further learn about it through research in which we are able to distinguish between centralized and decentralized exchanges.
