Binance Chain is great however the major issue is that its centralized. I think if there was a way to make it decentralized that many people would start using it. I am not surprised that the network activity increased on BSC because the fees for ETH were just pure crazy. Its nuts paying $10 for an ETH transaction or $25 for an ERC20 transaction or almost $100 for a DeFI transaction, hence why BSC started to gain network usage.
However I think most people don't want to make the switch because they are worried about its centrazliation issue. Which is very important to many people. Hence one of the reasons why alot of people don't like XRP since the owners have too much control. However people are making crazy money with all these projects that they don't really care at the moment.
I think fewer and fewer of these people, now a new generation of people who are open and open and they do not worry about their anonymity. We have to accept this, there are too few followers of anonymity.
